SMD 74HC138 - 3-to-8 line Decoder/Demultiplexer IC (74138 IC) 16-Pin SOIC-16 – [Original]

SMD 74HC138 - 3-to-8 Line Decoder/Demultiplexer IC (SOIC-16)

The SMD 74HC138 is a high-performance 3-to-8 line decoder/demultiplexer IC, perfect for a wide range of digital logic applications. Utilizing advanced silicon-gate CMOS technology, it offers an excellent balance of speed and efficiency. This integrated circuit boasts high noise immunity, ensuring reliable operation in various environments. Its low power consumption is a key advantage, making it suitable for energy-efficient designs. Despite its low power profile, the 74HC138 delivers speeds comparable to traditional low power Schottky TTL logic. It features three binary select inputs (A, B, and C) that control which of the eight normally HIGH outputs will go LOW when enabled. The device includes two active LOW and one active HIGH enables (G1, G2A, and G2B) for easy cascading of multiple decoders. Capable of driving 10 low power Schottky TTL equivalent loads, it's functionally and pin equivalent to the 74LS138. All inputs are protected against static discharge, enhancing durability and reliability.
