SN74AHC138PWR TI Decoder/Demultiplexer | 16-TSSOP | 3-to-8 Line, 2V to 5.5V

Product Overview

The SN74AHC138PWR is a high-performance 3-to-8 line decoder/demultiplexer from Texas Instruments, designed for 2V to 5.5V operation. It is fabricated using advanced CMOS technology to achieve high speed and low power consumption. The device accepts three binary address inputs (A0, A1, A2) and provides eight mutually exclusive active-low outputs (Y0–Y7). Three enable inputs (G1, G2A, G2B) allow for easy cascading and expansion. The SN74AHC138PWR is ideal for memory decoding, data routing, and digital system control applications.
