Benefits
• High supply voltage simplifies designs
by eliminating external parts
◦ Wide, +72V (max) single, power-
supply range; dual ±36V (max)
power-supply range
◦ Internal protection diodes can be
used for OVP
◦ Rail-to-rail operation allows a large
dynamic range
• Excellent R
ON
flatness for high-
accuracy measurements
◦ 0.03 (typ) R
ON
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 and
DG408/DG409
Eliminate External Overvoltage Protection
(OVP) Circuitry and Reduce BOM Complexity
with High-Voltage Multiplexers
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 0.03 (typ) R
ON
atness. Logic levels for the channel-select interface are
dened by the 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 MAX308/MAX309 and DG408/DG409. Both multiplexers
are specied over the extended -40°C to +85°C operating temperature range.
