Device is in production to support existing customers, but TI does not recommend using this part in a new design.PREVIEW: Device has been announced but is not in production. Samples may or may not be available.OBSOLETE: TI has discontinued the production of the device.(2)Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check /productcontent for the latest availability information and additional product content details.TBD: The Pb-Free/Green conversion plan has not been defined.Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)(3)MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.Important Information and Disclaimer:The information provided on this page represents TI's knowledge and belief as of the date that it is provided. TI bases its knowledge and belief on information provided by third parties, and makes no representation or warranty as to the accuracy of such information. Efforts are underway to better integrate information from third parties.

74HC164D中文资料参数SN54HC164,/SN74HC164是8位移位寄存器，当其中一个（或二个）选通串行输入端的低电平禁止进入新数据，并把第一个触发器在下一个时钟脉冲来后复位到低电平时，门控串行输入端（A 和B）可完全控制输入数据。

一个高电平输入后就使另一个输入端赋能，这个输入就决定了第一个触发器的状态。

虽然不管时钟处于高电平或低电平时，串行输入端的数据都可以被改变，但只有满足建立条件的信息才能被输入。

时钟控制发生在时钟输入由低电平到高电平的跃变上。

为了减小传输线效应，所有输入端均采用二极管钳位。

However,to ensure the high-impedance state above1.5V,OE should be tied to V CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.These devices are fully specified for hot-insertion applications using I off and power-up3-state.The I off circuitry disables the outputs,preventing damaging current backflow through the devices when they are powered down. The power-up3-state circuitry places the outputs in the high-impedance state during power up and power down, which prevents driver conflict.Please be aware that an important notice concerning availability,standard warranty,and use in critical applications of TexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.Widebus is a trademark of Texas

has announced that the device will be discontinued,and a lifetime-buy period is in effect.NRND:Not recommended for new designs.Device is in production to support existing customers,but TI does not recommend using this part in a new design.PREVIEW:Device has been announced but is not in production.Samples may or may not be available.OBSOLETE:TI has discontinued the production of the device.(2)Eco Plan -The planned eco-friendly classification:Pb-Free (RoHS),Pb-Free (RoHS Exempt),or Green (RoHS &no Sb/Br)-please check /productcontent for the latest availability information and additional product content details.TBD:The Pb-Free/Green conversion plan has not been defined.Pb-Free (RoHS):TI's terms "Lead-Free"or "Pb-Free"mean semiconductor products that are compatible with the current RoHS requirements for all 6substances,including the requirement that lead not exceed 0.1%by weight in homogeneous materials.Where designed to be soldered at high temperatures,TI Pb-Free products are suitable for use in specified lead-free processes.Pb-Free (RoHS Exempt):This component has a RoHS exemption for either 1)lead-based flip-chip solder bumps used between the die and package,or 2)lead-based die adhesive used between the die and leadframe.The component is otherwise considered Pb-Free (RoHS compatible)as defined above.Green (RoHS &no Sb/Br):TI defines "Green"to mean Pb-Free (RoHS compatible),and free of Bromine (Br)and Antimony (Sb)based flame retardants (Br or Sb do not exceed 0.1%by weight in homogeneous material)(3)MSL,PeakTemp.--The Moisture Sensitivity Level

TRANSLATION AND 3-STATE OUTPUTSSCES515H–DECEMBER 2003–REVISED JANUARY 2007The SN74LVC1T45is designed for asynchronous communication between two data buses.The logic levels of the direction-control (DIR)input activate either the B-port outputs or the A-port outputs.The device transmits data from the A bus to the B bus when the B-port outputs are activated and from the B bus to the A bus when the A-port outputs are activated.The input circuitry on both A and B ports always is active and must have a logic HIGH or LOW level applied to prevent excess I CC and I CCZ .The SN74LVC1T45is designed so that the DIR input is powered by V CCA .This device is fully specified for partial-power-down applications using I off .The I off circuitry disables the outputs,preventing damaging current backflow through the device when it is powered down.The V CC isolation feature ensures that if either V CC input is at GND,then both ports are in the high-impedance state.NanoFree™package technology is a major breakthrough in IC packaging concepts,using the die as the package.FUNCTION TABLE (1)INPUT OPERATION DIR L B data to A bus HA data toB bus(1)Input circuits of the data I/Os always are active.LOGIC

TRANSCEIVERWITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTSSCES515H–DECEMBER 2003–REVISED JANUARY 2007Figure 3shows the SN74LVC1T45being used in a bidirectional logic level-shifting application.Since the SN74LVC1T45does not have an output-enable (OE)pin,the system designer should take precautions to avoid bus contention between SYSTEM-1and SYSTEM-2when changing directions.The following table shows data transmission from SYSTEM-1to SYSTEM-2and then from SYSTEM-2to SYSTEM-1.STATE DIR CTRLI/O-1I/O-2DESCRIPTION1H Out In SYSTEM-1data to SYSTEM-2SYSTEM-2is getting ready to send data to SYSTEM-1.I/O-1and I/O-2are disabled.The 2H Hi-Z Hi-Z bus-line state depends on pullup or pulldown.(1)DIR bit is flipped.I/O-1and I/O-2still are disabled.The bus-line state depends on pullup or 3L Hi-Z Hi-Z pulldown.(1)4LOutInSYSTEM-2data to SYSTEM-1(1)SYSTEM-1and SYSTEM-2must use the same conditions,i.e.,both pullup or both pulldown.Figure 3.Bidirectional Logic Level-Shifting ApplicationCalculate the enable times for the SN74LVC1T45using the following formulas:•t PZH (DIR to A)=t PLZ (DIR to B)+t PLH (B to A)•t PZL (DIR to A)=t PHZ (DIR to B)+t PHL (B to A)•t PZH (DIR to B)=t PLZ (DIR to A)+t PLH (A to B)•t PZL (DIR to B)=t PHZ (DIR to A)+t PHL (A to B)In a bidirectional application,these enable times provide the maximum delay from the time the DIR bit is switched until an output is expected.For example,if the SN74LVC1T45initially is transmitting from A to B,then the DIR bit is switched;the B port of the device must be disabled before presenting it with an input.After the B port has been disabled,an input signal applied to it appears on the corresponding A port after the specified propagation delay.PACKAGING INFORMATIONOrderable Device Status (1)Package
