MAX4537CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4537CSE 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 on-resistance is 200Ω maximum, matched between channels to 4Ω maximum, and flat to 10Ω maximum over the signal range. Each switch handles rail-to-rail analog signals with off-leakage current of 1nA at +25°C and 10nA at +85°C. Digital inputs have 0.8V to 2.4V logic thresholds for TTL/CMOS compatibility. The device is housed in a 16-pin Narrow SO package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' corresponds to the commercial temperature range (0°C to +70°C) and the 16-pin Narrow SOIC package configuration. Confirm that the component meets RoHS compliance standards if required by the target assembly process. Ensure the ordering documentation matches the manufacturer's official part numbering system to avoid discrepancies in technical specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when replacing standard 74HC4316 devices with improved low-voltage performance. It is suitable for designs requiring normally closed switch configurations. Verify that the supply voltage range (+2V to +12V) aligns with the system power architecture. Consider the 200Ω on-resistance limit for signal integrity requirements in the specific application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4536/MAX4537/MAX4538 family of quad, low-voltage SPST analog switches. The MAX4537 variant specifically provides four normally closed switches, distinguishing it from the MAX4536 (normally open) and MAX4538 (mixed NO/NC). All three share identical pinouts and electrical characteristics, facilitating direct interchangeability within the same package types.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4537CSE is explicitly designed as a pin-compatible replacement for the 74HC4316. Designers should verify that the lower on-resistance and different leakage characteristics do not impact existing circuit timing or signal levels.
