74AHC139PW-Q100J

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74AHC139PW-Q100J is a dual 2-to-4 line decoder/demultiplexer in a TSSOP16 package. It decodes two binary weighted address inputs to four mutually exclusive outputs with an active LOW enable input. Qualified to AEC-Q100 Grade 1, it operates from -40 °C to +125 °C with a supply voltage of 2.0 V to 5.5 V. Inputs are overvoltage tolerant to 5.5 V and feature Schmitt-trigger action. Propagation delay ranges from 1.0 ns to 18.5 ns depending on load and voltage.

Signal Switches, Multiplexers, Decoders Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards for reliability.
• Dual independent decoder circuits with active LOW enable inputs for flexible configuration.
• Overvoltage tolerant inputs allow operation in mixed-voltage environments without damage.
• Schmitt-trigger inputs provide high noise immunity and clean signal transitions.

Signal Switches, Multiplexers, Decoders Applications

• Address decoding in automotive electronic control units
• Data routing in multiplexer/demultiplexer configurations
• Memory chip select generation in vehicle infotainment systems

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'J' against the manufacturer's current ordering information to confirm packaging details such as tape and reel specifications. Confirm that the TSSOP16 package variant matches the required board layout dimensions. Ensure the AEC-Q100 Grade 1 qualification status meets the specific automotive application requirements before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual independent decoding or demultiplexing is required in space-constrained automotive designs. The wide supply voltage range supports various logic levels. Verify that the operating temperature range up to +125 °C aligns with the thermal environment of the target application. Consider the overvoltage tolerance if interfacing with 5 V signals while powered by lower voltages.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the Nexperia 74AHC139-Q100 family of automotive-grade logic ICs. It shares functional characteristics with other members of the series but differs in package type and specific electrical parameters defined by the AHC technology. The PW suffix indicates the TSSOP16 plastic thin shrink small outline package, distinguishing it from SO16 variants.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as the 74AHCT139PW-Q100J, which offers TTL input levels instead of CMOS levels. Verify that any substitute maintains the AEC-Q100 Grade 1 qualification and the TSSOP16 package form factor to ensure mechanical compatibility.
