General Description

The MAX4598 low-voltage, CMOS analog IC is a con-

figurable single-ended 8-to-1/differential 4-to-1 multi-

plexer. In addition to the input channels, both V+ and

GND can be switched to the output channels, enabling

the supply voltages to be monitored. The MAX4598

operates from a single +2.7V to +12V supply or from

dual ±6V supplies. The device has low on-resistance

(75

Ω max) and TTL-compatible logic inputs from either

±5V or a single +5V supply. Each switch can handle

modes of operation: as a standard multiplexer and as a

“latchable” multiplexer where the address lines are

per Method 3015.7.

The MAX4598 is available in small 20-pin SSOP, SO,

and DIP packages.
