A 3-to-8 line decoder/demultiplexer is a digital logic component that takes a binary input and selects one of the eight output lines based on the input value.
The 74HCT138, 74HC138 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC138 / 74HCT138 decoders accept three binary weighted address inputs (A0, A1, A2) and when enabled, provide 8 mutually exclusive active LOW outputs (Y0 to Y7).
