Programmable logic controllers (PLCs)

Analog input function

Benefits

• High supply voltage eliminates external

OVP diodes and opto relays

– Wide, single 72V (max) power-supply

range; dual ±36V (max) power-supply

range

– Internal protection diodes can be used

for OVP

– Rain-to-rail operation gives large

dynamic range

• Excellent R

flatness for high-

accuracy measurements

– 0.03Ω (typ) R

flatness over

common-mode voltage

• Flexible logic levels for interfacing with

multivoltage systems

– Device enable (EN) defines voltage logic

level of channel-select inputs

• Easy upgrade path

– Pin compatible with industry-standard

MAX308/MAX309/DG408/DG409

MAX14752/MAX14753

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

high-voltage analog multiplexers designed for high-voltage PLC

applications. Both devices operate with dual supplies of ±10V to ±36V

or a single supply of 20V to 72V, and a low 0.03Ω (typ) R

flatness.

Logic levels for the channel-select interface are defined by the device

enable (EN) input to help interface with multivoltage systems. The

MAX14752/MAX14753 are packaged in the standard 16-pin TSSOP,

and are pin compatible with the industry-standard DG408/DG409.

Both multiplexers are specified over the extended -40°C to +85°C

operating temperature range.

Eliminate external overvoltage protection (OVP) circuitry and reduce BOM complexity

with high-voltage multiplexers
