74AHCT139PW-Q100J

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74AHCT139PW-Q100J is a dual 2-to-4 line decoder/demultiplexer housed in a TSSOP16 (SOT403-1) package. It decodes two binary weighted address inputs to four mutually exclusive outputs, each with an active LOW enable input. The device features overvoltage tolerant inputs up to 5.5 V, allowing use as translators in mixed voltage environments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. Qualified to AEC-Q100 Grade 1 standards, it includes Schmitt-trigger inputs for high noise immunity.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range specifications. Ensure compatibility with AEC-Q100 Grade 1 requirements for automotive deployments. Cross-reference pin assignments and electrical characteristics with the latest product data sheet revision before finalizing design integration.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual independent decoding or demultiplexing functions are required in space-constrained designs utilizing the TSSOP16 package. The AHCT variant ensures TTL-compatible input levels while maintaining CMOS performance. Verify that the operating voltage remains within the 4.5 V to 5.5 V range and that thermal conditions stay within the specified -40 °C to +125 °C operational limits.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the Nexperia 74AHC/AHCT139-Q100 family of dual 2-to-4 line decoders. It shares functional similarities with other members of the series but differs in input logic level compatibility and specific package options. The PW suffix denotes the TSSOP16 plastic thin shrink small outline package, distinguishing it from SO16 variants.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes include the 74AHC139PW-Q100J for CMOS-level input applications. For non-automotive contexts, standard 74AHCT139PW variants may be considered if AEC-Q100 qualification is not required. Verify pinout and electrical parameters match before substitution.
