MAX4621EPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4621EPE is a dual, high-speed analog switch featuring two single-pole/single-throw (SPST) channels in a 16-pin Plastic DIP package. It operates from a single supply of +4.5V to +36V or bipolar supplies of ±4.5V to ±18V. The device guarantees a maximum on-resistance of 5Ω with a channel-to-channel match of 0.5Ω max and flatness of 0.5Ω max over the signal range. Switching times are fast, with turn-on under 250ns and turn-off under 200ns. Leakage current remains below 5nA at +85°C. Logic inputs are TTL/CMOS compatible.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Rail-to-Rail analog signal handling capability for precision applications
• TTL/CMOS-compatible logic inputs for direct interface with digital control systems

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• Audio-signal routing and data-acquisition systems
• Military radios and avionics communication systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EPE confirms the -40°C to +85°C industrial temperature range and 16-PDIP package configuration. Ensure the ordering code matches the exact manufacturer specifications for the MAX4621 series to avoid functional mismatches with other variants like the MAX4622 or MAX4623.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and precise resistance matching are required. It serves as a pin-compatible upgrade for older DG401 designs. Verify that the application requires dual SPST switches rather than the SPDT configuration found in the MAX4622 variant.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4621/MAX4622/MAX4623 family of precision analog switches. These devices were designed to replace mechanical relays and earlier CMOS switches like the DG401, offering superior performance in switching speed and reliability while maintaining a compact footprint.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4621EPE is a direct pin-compatible replacement for the Intersil DG401CPE and DG401EPE. Designers upgrading from these legacy parts should verify that the new voltage and leakage specifications meet the system requirements.

Analog Switches, Multiplexers, Demultiplexers FAQ

Is the MAX4621EPE break-before-make?

No, the MAX4621EPE consists of normally open SPST switches and does not feature break-before-make timing. This function is available only in the MAX4622 variant.

What is the maximum continuous current rating?

The absolute maximum ratings specify a continuous current of ±100mA through the COM_, NO_, or NC_ pins.

How does the MAX4621 compare to the DG401?

The MAX4621 is a pin-compatible replacement for the DG401, offering improved overall performance including lower on-resistance and faster switching speeds.
