MAX359EWE+ Datasheet PDF - Maxim Integrated

●The MAX359EWE+ is a 4-channel differential fault-protected analogue multiplexer in 16 pin WSOIC 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 -40°C to 85°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

● Access time is 0.5µs
