MAX4538CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4538CSE+ is a quad, low-voltage, single-pole/single-throw (SPST) analog switch featuring a common enable pin. It contains two normally open and two normally closed switches. The device operates from +2V to +12V single supplies or ±2V to ±6V dual supplies. On-resistance is 200Ω maximum, matched between channels to 4Ω maximum, with flatness of 10Ω maximum over the signal range. It handles rail-to-rail analog signals with off-leakage current of 1nA at +25°C and 10nA at +85°C. Logic inputs have 0.8V to 2.4V thresholds for TTL/CMOS compatibility. Turn-on time is 125ns maximum and turn-off time is 100ns maximum at ±5V supplies.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the C suffix indicates the commercial temperature range of 0°C to +70°C. Confirm the SE suffix corresponds to the 16-pin Narrow SO package. Ensure the datasheet revision matches the design requirements. Check RoHS compliance status as indicated in the ordering information section.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a common enable control for multiple SPST switches is required. The MAX4538 provides mixed NO and NC configurations within a single package. Verify that the supply voltage range meets the system's power constraints. Ensure the on-resistance specifications are sufficient for the intended signal levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4536/MAX4537/MAX4538 family of quad low-voltage analog switches. The MAX4536 offers four normally open switches, while the MAX4537 provides four normally closed switches. The MAX4538 combines two normally open and two normally closed switches in one package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4536 and MAX4537 are pin-compatible alternatives within the same family. The 74HC4316 is an industry-standard equivalent offering similar functionality.
