General Description

The MAX14752/MAX14753 are 8-to-1 and dual 4-to-1

high-voltage analog multiplexers. Both devices feature

60Ω (typ) on-resistance with 0.03Ω (typ) on-resistance

flatness. These low on-resistance multiplexers conduct

equally well in either direction. Flexible logic levels for

the channel-select interface are defined by the EN input.

The MAX14752 is a 8-to-1 multiplexer and MAX14753 is

a dual 4-to-1 multiplexer. Both devices operate with

dual supplies of ±10V to ±36V, or a single supply of

+20V to +72V.

The MAX14752/MAX14753 are available in a 16-pin

TSSOP package and are pin compatible with the indus-

try-standard DG408/DG409. Both the MAX14752/

MAX14753 are specified over the extended -40°C to

+85°C operating temperature range.
