74HCT139D Description

Short technical summary and product information.

The 74HCT139D from NXP Semiconductors is a versatile dual 2-to-4 line decoder/demultiplexer IC. Each decoder within the package features an enable input and decodes two binary weighted address inputs to four mutually exclusive outputs. When the enable input is HIGH, all outputs are forced HIGH. This device is suitable for applications such as memory decoding, data routing, and code conversion.

 

Key features include demultiplexing capability and two independent 2-to-4 decoders. The input levels can be either CMOS or TTL, depending on the specific variant (74HC139 for CMOS, 74HCT139 for TTL). The outputs are active LOW and mutually exclusive. The device is specified for operation over a wide temperature range of -40 °C to +125 °C.

 

Available in SO16 and TSSOP16 packages, the 74HCT139D is designed for surface mount applications. It complies with JEDEC standard no. 7A and offers ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

 

This component is ideal for digital logic designs requiring address decoding or data distribution functions. Its dual decoder architecture allows for efficient implementation of complex control logic.
