MAX4538CSE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4538CSE+T is a quad, low-voltage, single-pole/single-throw (SPST) analog switch featuring two normally open and two normally closed channels with a common enable pin. It operates from +2V to +12V single supplies or ±2V to ±6V dual supplies. The device offers a maximum on-resistance of 200Ω, matched between channels to 4Ω max, with flatness of 10Ω max over the signal range. Logic inputs are TTL/CMOS-compatible at +5V. The package is a 16-pin Narrow SOIC.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' corresponds to the commercial temperature range (0°C to +70°C) and the Narrow SOIC package format. Confirm RoHS compliance status via the manufacturer's official documentation before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mix of normally open and normally closed switching paths is required within a single package. Ensure the supply voltage range aligns with the system's power rails, as logic thresholds vary with V+. Consider the break-before-make timing if sequential switching is critical.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4536/MAX4537/MAX4538 family of quad SPST analog switches. While the MAX4536 provides four normally open switches and the MAX4537 provides four normally closed switches, the MAX4538 combines two of each type. All three share identical pinouts and electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4536CSE+T and MAX4537CSE+T are pin-compatible alternatives within the same series. Verify that the specific switch configuration (NO vs NC) meets the circuit requirements before substituting.
