MAX4537EEE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4537EEE is a quad, low-voltage, single-pole/single-throw (SPST) analog switch with a common enable pin. It features four normally closed switches and operates from +2V to +12V single supplies or ±2V to ±6V dual supplies. The device has a maximum on-resistance of 200Ω, matched between channels to 4Ω max, with flatness of 10Ω max. Logic thresholds are 0.8V to 2.4V for TTL/CMOS compatibility at +5V. Switching times are 100ns turn-on and 80ns turn-off at ±4.5V. It offers 1nA off-leakage current at +25°C and >2kV ESD protection. The component is housed in a 16-pin QSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix 'EEE' corresponds to the -40°C to +85°C temperature range and 16-pin QSOP package configuration. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure supply voltage limits do not exceed absolute maximum ratings during operation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed SPST configuration is required for low-voltage applications. Verify that the 200Ω maximum on-resistance meets system impedance requirements. Ensure the operating temperature range covers the intended environmental conditions. Check logic level compatibility if using supply voltages other than +5V.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4537EEE belongs to the MAX4536/MAX4537/MAX4538 family of quad analog switches. Unlike the MAX4536 which uses normally open switches, the MAX4537 utilizes normally closed switches. The MAX4538 combines both types. All three variants share identical pinouts and electrical characteristics except for the switch state logic.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4536EEE serves as a functional substitute if normally open switches are acceptable instead of normally closed. The MAX4538EEE provides mixed NO/NC configurations within the same package.
