Description and Introduction
High Speed CMOS Logic 3-to-8 Line Decoder/Demultiplexer Inverting and Non-Inverting # Introduction to the CD74HCT138M96 Decoder/Demultiplexer  
The **CD74HCT138M96** from Intersil is a high-speed CMOS logic device designed as a 3-to-8 line decoder/demultiplexer. Built with silicon-gate CMOS technology, it combines low power consumption with the high noise immunity and drive capabilities typical of HCT-series logic.   This IC is widely used in digital systems for address decoding, data routing, and memory selection. It features three binary select inputs (A0, A1, A2) that determine which of the eight active-low outputs (Y0-Y7) will be enabled. Three enable inputs (two active-low and one active-high) ensure flexible control, allowing the device to function only when required, reducing power dissipation.   The **CD74HCT138M96** operates within a supply voltage range of **4.5V to 5.5V**, making it compatible with standard TTL levels while maintaining CMOS-level power efficiency. With a typical propagation delay of **15 ns**, it is suitable for high-speed applications.   Packaged in a **SOIC-16** form factor, this decoder/demultiplexer is ideal for space-constrained designs. Its robust performance and reliability make it a preferred choice in industrial, automotive, and consumer electronics where precise signal routing is essential. |
