MAX4538CEE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4538CEE is a quad, low-voltage, single-pole/single-throw (SPST) analog switch featuring two normally open and two normally closed switches with a common enable pin. It operates from +2V to +12V single supplies or ±2V to ±6V dual supplies. The device offers rail-to-rail signal handling, on-resistance of 200Ω max matched to 4Ω, and off-leakage current of 1nA at +25°C. Logic inputs are TTL/CMOS-compatible with thresholds of 0.8V to 2.4V. It provides >2kV ESD protection and consumes less than 1µW power. The component is housed in a 16-pin QSOP package and functions within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CEE' corresponds to the 16-pin QSOP package and the commercial temperature range of 0°C to +70°C. Confirm that the ordering information matches the manufacturer's current documentation, as availability may vary by region. Ensure the source document explicitly lists this part number before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4538CEE when a mix of normally open and normally closed SPST switches is required in a single package. It is suitable for applications requiring low voltage operation down to +2V. Consider the break-before-make timing if switching between paths is critical. Verify that the 200Ω maximum on-resistance meets the system's signal integrity requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4536/MAX4537/MAX4538 family of quad analog switches. While the MAX4536 contains four normally open switches and the MAX4537 contains four normally closed switches, the MAX4538 combines two of each type. All three variants share identical pinouts and electrical characteristics regarding supply ranges and leakage currents.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet states the device is pin compatible with the 74HC4316. Designers should verify that the 74HC4316 meets the specific on-resistance and leakage requirements of the original design before substitution.
