MAXIM MAX14752, MAX14753 User Manual

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 indus­try-standard DG408/DG409. Both the MAX14752/
MAX14753 are specified over the extended -40°C to
+85°C operating temperature range.

ABSOLUTE MAXIMUM RATINGS

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
