Low-Voltage, Combination Single-Ended
8-to-1/Differential 4-to-1 Multiplexer
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
(75Ω max) and TTL-compatible logic inputs from either
±5V or a single +5V supply. Each switch can handle
Rail-to-Rail
®
analog signals. The MAX4598 has two
modes of operation: as a standard multiplexer and as a
“latchable” multiplexer where the address lines are
strobed. The off-leakage current is only 0.1nA at T
A
=
+25°C and 2nA at T
A
= +85°C. ESD protection is > 2kV
per Method 3015.7.
The MAX4598 is available in small 20-pin SSOP, SO,
and DIP packages.

Note 1:
Signals on NO_, COM_, EN, LATCH, NLATCH, or A_ exceeding V+ or V- are clamped by internal diodes. Limit forward cur-
rent to maximum current 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.
