MAX4533CAP

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4533CAP is a quad, single-pole/double-throw (SPDT) analog switch featuring fault protection and rail-to-rail signal handling. It operates from dual ±4.5V to ±18V supplies or a single +9V to +36V supply. The device provides ±25V fault protection with power on and ±40V with power off. On-resistance is 175Ω maximum at ±15V supplies, with channel matching of 10Ω maximum. Off-leakage current is 0.5nA at +25°C. Logic inputs are TTL/CMOS compatible. The component is housed in a 20-pin SSOP package and functions within an operating temperature range of 0°C to +70°C.
