MAXIM DG201A, DG211 User Manual

General Description
The 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 primari­ly 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 (VL) power supply that is required for the oper­ation of the original manufacturer’s DG211.
