SN74HCT139PWR TI Decoder/Demultiplexer | 16-TSSOP | 2-to-4 Line, Dual

Product Overview

The SN74HCT139PWR from Texas Instruments is a dual 2-to-4 line decoder/demultiplexer designed for high-speed CMOS logic applications. It features two independent decoders, each accepting two binary inputs (A0, A1) and providing four mutually exclusive active-low outputs (Y0–Y3). The device is fabricated using silicon-gate CMOS technology, achieving typical propagation delays of 10 ns while maintaining low power consumption. It operates over a wide supply voltage range of 4.5 V to 5.5 V, making it compatible with TTL logic levels. The 16-pin TSSOP package (PW) offers a compact footprint for space-constrained designs.
