74AHC139PW,118

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74AHC139PW,118 is a dual 2-to-4 line decoder/demultiplexer housed in a 16-TSSOP package. It decodes two binary weighted address inputs to four mutually exclusive outputs. The device operates on a single power supply ranging from 2.0 V to 5.5 V and features Schmitt-trigger inputs for high noise immunity. Outputs are active LOW, and the enable input can function as data input for demultiplexing.

Signal Switches, Multiplexers, Decoders Feature Summary

• Decodes two binary weighted address inputs to four mutually exclusive outputs
• Features Schmitt-trigger action at all inputs for improved noise immunity
• Inputs are overvoltage tolerant up to 5.5 V for mixed voltage translation
• CMOS low power dissipation with latch-up performance exceeding 100 mA

Signal Switches, Multiplexers, Decoders Applications

• Address decoding in memory systems
• Data routing via demultiplexer configuration
• Mixed voltage level translation between logic families

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm RoHS compliance status against current regulatory requirements. Check for any recent Product Change Notifications regarding assembly or labeling updates before finalizing procurement specifications.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a dual decoder or demultiplexer is required within a 16-pin surface mount footprint. Ensure the application voltage falls within the 2.0 V to 5.5 V range. Consider the TSSOP package dimensions if board space is constrained compared to standard SO packages.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74AHC series of high-speed CMOS logic devices manufactured by Nexperia. It shares functional compatibility with other 74AHC139 variants but utilizes the PW (TSSOP) packaging style. The '118' suffix indicates the specific tape and reel or cut tape packaging configuration provided by the manufacturer.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes include the 74AHCT139PW,118 for TTL-compatible input levels. Other compatible alternatives may include parts from different manufacturers offering identical pinouts and logical functions within the same package type.
