MAX4538EPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4538EPE 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 on-resistance is 200Ω maximum at +4.5V single supply and 100Ω maximum at ±5V dual supplies, with a flatness of 10Ω maximum. Off-leakage current is 1nA at +25°C and 10nA at +85°C. Logic inputs are TTL/CMOS-compatible, and the device provides over 2kV ESD protection per Method 3015.7.

• Audio-signal routing
• Avionics applications

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EPE' corresponds to the -40°C to +85°C temperature range and 16-pin Plastic DIP package as defined in the official ordering information. Confirm that the component meets RoHS compliance standards required for the target assembly process before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a mix of normally open and normally closed channels is required within a single package. Ensure the application voltage does not exceed the absolute maximum ratings, particularly the V+ to V- differential limit of 13.0V, to prevent permanent damage during operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4536/MAX4537/MAX4538 family of quad SPST analog switches. While the MAX4536 offers four normally open switches and the MAX4537 provides four normally closed switches, the MAX4538 uniquely combines two of each type. All variants share identical pinouts and electrical characteristics regarding speed and leakage.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4538EPE is pin-compatible with the 74HC4316. Designers replacing legacy 74HC4316 components should verify that the lower on-resistance and different logic thresholds of the MAX4538 do not impact existing circuit timing or drive requirements.
