General Description
The DG201A and DG211 are normally clod, quad single-pole single-throw (SPST) analog switches. The CMOS switches can be continuously operated with power supplies ranging from ±4.5V to ±18V. Maxim guarantees that the switches will not latch up if the power supplies are disconnected with input signals still connected.王母宫
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.

Pin Description
Switching Time Test Circuit
Switch output waveform shown for V S = constant with logic input waveform as shown. 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.
