MAX4533EPP

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4533EPP is a quad, single-pole/double-throw (SPDT) analog switch featuring rail-to-rail signal handling and fault protection. 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, matched to 10Ω maximum between channels. Off-leakage current is 0.5nA at +25°C and 10nA at +85°C. Logic inputs are TTL/CMOS compatible with thresholds of +0.8V and +2.4V. The component is housed in a 20-pin Plastic DIP package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EPP corresponds to the 20-pin Plastic DIP package variant when sourcing. Confirm the extended temperature grade (-40°C to +85°C) matches system requirements. Check for RoHS compliance status as indicated in official documentation. Ensure availability aligns with current manufacturing schedules.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring high-voltage fault tolerance without power. Verify that the 175Ω on-resistance meets signal integrity needs. Ensure supply voltages remain within the specified ±4.5V to ±18V dual or +9V to +36V single ranges. Consider the 20-pin DIP footprint for PCB layout compatibility.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4533 series includes variants like MAX4533CAP and MAX4533CWP for commercial temperatures, and MAX4533MJP for military grades. The EPP suffix specifically denotes the industrial temperature range version in a plastic DIP package. It serves as a direct pin-compatible replacement for older MAX333 designs while offering improved fault protection.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4533 handle overvoltage faults?

During a fault condition where input exceeds supply rails, the NO_ and NC_ terminals become high impedance. The COM_ output clamps to the appropriate polarity supply rail, providing up to ±10mA of load current.

What is the logic voltage compatibility?

All digital inputs have +0.8V and +2.4V logic thresholds, ensuring both TTL and CMOS logic compatibility when using ±15V supplies or a +12V supply.

Is power-supply sequencing required?

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