General DescriptionThe DG201A and DG211 are normally closed, quad single-pole single-throw (SPST) analog switches. These CMOS switches can be continuously operated with power supplies ranging from ±4.5V to ±18V. Maxim guarantees that these switches will not latch up if the power supplies are disconnected with input signals still connected.Both devices have guaranteed break-before-make switching. The DG201A differs from the DG211 primari-ly in switching speeds. The DG201A has a maximum turn-off time of 450ns and a maximum turn-on time of 600ns. The DG211 has a maximum turn-off time of 500ns and a maximum turn-on time of 1000ns.Compared to the original manufacturer’s products,Maxim’s DG201A and DG211 consume significantly lower power making them better suited for portable applications. Maxim has also eliminated the need for the third (V L ) power supply that is required for the oper-ation of the original manufacturer’s DG211.ApplicationsWinchester Disk Drives Test EquipmentCommunications Systems PBX, PABXGuidance and Control Systems Head Up Displays Military RadiosFeatures♦Guaranteed ±4.5V to ±18V Operation ♦No V L Supply Required♦Nonlatching with Supplies Turned Off and Input Signals Present ♦CMOS and TTL Logic Compatible ♦Monolithic, Low-Power CMOS DesignDG201A/DG211Quad SPST CMOS Analog Switches________________________________________________________________Maxim Integrated Products 1Pin ConfigurationsOrdering Information19-3959; Rev 2; 5/06For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Typical Operating CircuitPin Configurations continued at end of data sheet.D G 201A /D G 211Quad SPST CMOS Analog Switches 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGS (DG211)ELECTRICAL CHARACTERISTICS (DG211)(V+ = +15V, V- = -15V, GND = 0, T A = +25°C, unless otherwise noted.)

Note that V S may be +ve or -ve as per switching times test circuit. V O is the steady state output with switch on. Feedthrough via gate capacitance may result in spikes at leading and trailing edge of output waveform.D G 201A /D G 211Quad SPST CMOS Analog Switches 6_______________________________________________________________________________________Protecting Against FaultConditionsFault conditions occur when power supplies are turned off when input signals are still present, or when over-voltages occur at the inputs during normal operation. In either case, source-to-body diodes can be forward biased and conduct current from the signal source. If this current is required to be kept to low (µA) levels then the addition of external protection diodes is rec-ommended.To provide protection for overvoltages up to 20V above the supplies, a 1N4001 or 1N914 type diode should be placed in series with the positive and negative supplies as shown in Figure 2. The addition of these diodes will reduce the analog signal range to 1V below the posi-tive supply and 1V above the negative supply.Figure 2. Protection against Fault ConditionsFigure 1.
