19-3960; Rev 3; 6/06 Quad SPST CMOS Analog Switches The DG202/DG212 are normally open, quad singlepole 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. The DG202/DG212 are similar to the DG201/DG211 except for inverted control inputs. All devices have guaranteed break-before-make switching, as well as essentially constant on-resistance over the analog signal range. All switches conduct current in either direction and add no offset to the output signal. Compared to the original manufacturer’s products, Maxim’s DG202/DG212 consume very little power, making them better suited for portable applications. Maxim has also eliminated the need for the third logic power supply (VL) that is required for the operation of the original manufacturer’s DG212 without sacrificing compatibility.

Note that VS may be +ve or -ve as per switching times test circuit. VO is the steady state output with switch on. Feedthrough via gate capacitance may result in spikes at leading and trailing edge of output waveform. Protecting Against Fault Conditions Fault conditions occur when power supplies are turned off when input signals are still present, or when overvoltages 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.
