The MAX359CPE+ is a 4-channel differential fault-protected analogue multiplexer in 16 pin DIP package. This fault-protected multiplexer use a series NPN structure (Field effect transistor) that protects the device from overvoltage up to ±35V beyond the supply rail. This device not only protects from overvoltage but also limits the fault currents to nanoamp leakage values rather than milli amperes. This protects multiplexer as well as sensors and other sensitive signal sources which are driven by multiplexer. All digital inputs have 0.8V and 2.4V logic thresholds ensuring both TTL and CMOS logic compatibility without pull-up resistors. Break-before-make operation is guaranteed and power consumption is less than 2mW. Typical applications include data acquisition systems, ATE equipment, signal routing and redundant/backup systems.
Supply voltage range is ±4.5V to ±18V
Operating temperature range from 0°C to 75°C
Maximum on resistance is 1.8Kohm
On switch turns off with overvoltage
All switches off with supplies off
Latch-up proof construction
1nA max off input leakage current and 2nA off output leakage current at +25°C
