MAX4533EAP

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4533EAP+ 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, matched between channels to 10Ω maximum. Off-leakage current is 0.5nA at +25°C and 10nA at +85°C. Logic inputs are TTL/CMOS compatible. The component is housed in a 20-pin SSOP package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4533 handle overvoltage faults?

During a fault condition where NO_ or NC_ exceeds the supply rails, the output COM_ clamps to the appropriate polarity supply rail, providing up to ±10mA of load current while maintaining high impedance at the faulted input.

Is power-supply sequencing required during operation?

No power-supply sequencing is required during power-up or power-down. All switches turn off automatically when power is removed.

What is the typical fault response time?

The typical fault response time is 20ns, allowing the switch to quickly disconnect the output from the overvoltage source.
