Rochester Electronics Interface - Analog Switches, Multiplexers, Demultiplexers MAX4533CPP

The MAX4533CPP is a quad, single-pole/double-throw (SPDT) analog switch designed for fault protection and rail-to-rail signal handling. It is pin-compatible with the MAX333 and MAX333A, making it suitable for applications requiring a seamless transition from existing designs. The device can handle overvoltage faults up to ±25V with power on and ±40V with power off, ensuring high reliability in fault conditions. The switch outputs clamp to the appropriate supply rail during faults, minimizing transition glitches. Operating from dual ±4.5V to ±18V power supplies or a single +9V to +36V supply, the MAX4533CPP features TTL and CMOS logic compatibility with input thresholds of +0.8V and +2.4V. The on-resistance is a maximum of 175,Ѷ, with a matching tolerance of 10,Ѷ between switches. Off-leakage current is low, at 0.5nA at +25°C, making it suitable for precision applications. The device is ideal for use in redundant systems, portable instruments, test equipment, and industrial control systems.
