74HCT139PW,118

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74HCT139PW,118 is a dual 2-to-4 line decoder/demultiplexer housed in a 16-TSSOP package. It features two independent decoders with active LOW mutually exclusive outputs and an enable input (nE) for demultiplexing. The device operates on a single power supply ranging from 4.5 V to 5.5 V. It supports an ambient temperature range of -40 °C to +125 °C and includes ESD protection exceeding 2000 V (HBM). Inputs utilize clamp diodes to interface with voltages exceeding VCC.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and tape/reel specifications. Confirm that the component meets all required environmental and electrical standards for the intended application before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when TTL-level inputs are required within a CMOS system. Ensure the design accommodates the specified voltage range and operating temperature limits. Verify pin compatibility if replacing existing designs using different package variants.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74HCT series of logic ICs manufactured by Nexperia. It is functionally compatible with other 74HCT139 variants but utilizes a TSSOP16 package (SOT403-1) instead of the SO16 package found in other versions like the 74HCT139D.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check datasheets for alternative packages such as the 74HCT139D (SO16) to confirm pinout and electrical equivalence before substitution.
