The MAX331, 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.
All three devices have a guaranteed break-before-make switching. The MAX331 and DG201A differ from the DG211 primarily in switching speeds. The MAX331 and DG201A have 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.
