CD54HCT139 Datasheet Dual 2- To 4-line Decoder/demultiplexer

Manufacturer: Texas Instruments

This datasheet includes multiple variants, all published together in a single manufacturer document.

CD54HCT139 Overview

If the enable input is high all four outputs remain high. For demultiplexer operation the enable input is the data input. The enable input also functions as a chip select when these devices are cascaded. This device is functionally the same as the CD4556B and is pin patible with it. 1 (15) E 4 (12) Y0
