Product Overview
The SN74HCT138NSR is a 3-to-8 line decoder/demultiplexer from Texas Instruments, designed for high-speed CMOS logic applications. It features three binary select inputs (A, B, C) and three enable inputs (G1, G2A, G2B) to control the decoding function. The device is ideal for memory decoding, data routing, and general-purpose logic applications. Housed in a 16-pin SOIC package, it offers a compact solution for space-constrained designs.
