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
♦ V+ and GND Can Be Switched to the Output
Channels
♦ 75Ω (max) On-Resistance
♦ Single-Ended or Differential Operation
♦ 2pC (typ) Charge Injection
♦ Latched or Unlatched Operation
♦ TTL-Compatible Logic Inputs at ±5V Supply
♦ Handles Rail-to-Rail Analog Signals
strobed. The off-leakage current is only 0.1nA at T

+25°C and 2nA at T = +85°C. ESD protection is > 2kV
per Method 3015.7.
