MAX4538EEE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4538EEE is a quad, low-voltage, single-pole/single-throw (SPST) analog switch with a common enable pin. It features 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 max, matched between channels to 4Ω max, and flat to 10Ω max over the signal range. Each switch handles rail-to-rail analog signals. Off-leakage current is 1nA at +25°C and 10nA at +85°C. Digital inputs have 0.8V to 2.4V logic thresholds for TTL/CMOS compatibility. Turn-on time is 100ns and turn-off time is 80ns at ±4.5V supply. Power consumption is less than 1µW.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EEE' corresponds to the -40°C to +85°C extended temperature range and QSOP-16 package configuration as defined in the official ordering information. Confirm that the component meets RoHS standards if required by the design specifications. Ensure the source documentation explicitly lists this part number variant to avoid confusion with other temperature grades or package styles within the same family.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4538EEE when a mixed configuration of normally open and normally closed SPST switches is required within a single package. This part is suitable for designs needing a common enable control for all four channels. Consider the on-resistance characteristics and leakage currents relative to the intended signal voltage range and operating temperature conditions specified in the electrical characteristics tables.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4538EEE belongs to the MAX4536/MAX4537/MAX4538 family of quad, low-voltage SPST analog switches. While the MAX4536 provides four normally open switches and the MAX4537 offers four normally closed switches, the MAX4538 combines two of each type. All variants share identical pinouts and electrical performance profiles, differing only in the internal switch state configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4538EEE is pin-compatible with the industry-standard 74HC4316. Designers replacing legacy 74HC4316 components should verify that the lower on-resistance and different power supply requirements of the MAX4538 are acceptable for the existing circuit topology.
