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 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

) power supply that is required for the oper-

ation of the original manufacturer’s DG211.
