74HCT139D Description

Short technical summary and product information.

The 74HCT139D from Texas Instruments 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. The enable input, when HIGH, forces all outputs HIGH. This functionality allows the enable input to be utilized as a data input in 1-to-4 demultiplexer applications.

 

This component is suitable for various applications including memory decoding, data routing, and code conversion. It complies with JEDEC standard no. 7A. The device offers active LOW outputs and includes clamp diodes on its inputs, enabling the use of current-limiting resistors for interfacing with voltages exceeding VCC.

 

The 74HCT139D is available in SO16 and TSSOP16 packages. It is specified for operation over a wide temperature range of -40 °C to +125 °C. ESD protection is provided, meeting HBM class 2 and CDM class C3 standards.
