Product Overview
The SN74HCT138PWT 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 functions in systems requiring low power consumption and high noise immunity. Packaged in a 16-TSSOP, it offers a compact footprint for space-constrained designs.
