SN74AHC139PWR

Signal Switches, Multiplexers, Decoders Overview

The SN74AHC139PWR is a dual 2-to-4-line decoder/demultiplexer from the Texas Instruments SN74AHC139 series. It operates within a supply voltage range of 2 V to 5.5 V and features a propagation delay of 10.5 ns. The device supports a wide operating temperature range from -40°C to +125°C. It is housed in a 16-TSSOP package with surface-mount installation. The component contains two independent circuits, each providing one 2-to-4 decoding function.

Signal Switches, Multiplexers, Decoders Feature Summary

• Dual independent 2-to-4 line decoding functionality
• Wide supply voltage operation from 2 V to 5.5 V
• Extended industrial temperature range up to 125°C

Signal Switches, Multiplexers, Decoders Applications

• Address decoding for memory and I/O port selection
• Demultiplexing data signals in digital systems
• Control logic in automotive electronic modules

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix PWR corresponds to the TSSOP-16 package and reel packaging configuration. Confirm RoHS compliance status and ensure the manufacturer part number matches the required automotive or industrial grade specifications before procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual independent decoding is required within a single package. The AHC series offers high-speed performance compatible with standard CMOS logic levels. Ensure the system voltage falls within the 2 V to 5.5 V range and thermal requirements are met by the extended temperature rating.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN74AHC139 family of decoders and demultiplexers. It shares functional similarities with other variants like SN74AHC139DGVR but differs in package type. The PWR suffix indicates a plastic small-outline package suitable for surface-mount technology applications.

Signal Switches, Multiplexers, Decoders Replacement Considerations

SN74AHC139DGVR serves as a direct substitute with identical logical functions but utilizes a TVSOP-16 package instead of TSSOP-16.
