SN74HCT139N TI Decoder/Demultiplexer | 16-PDIP | 2-to-4, Dual

Product Overview

The SN74HCT139N is a dual 2-to-4 line decoder/demultiplexer from Texas Instruments, designed with HCT technology for high-speed CMOS logic. It features two independent decoders, each accepting two binary inputs (A0, A1) and providing four mutually exclusive active-low outputs (Y0–Y3). The device includes an active-low enable input (G) for each decoder, allowing flexible control. Housed in a 16-pin PDIP package, it is ideal for memory decoding, data routing, and general-purpose logic applications.
