MC74HC138ADR2G Description

Short technical summary and product information.

The MC74HC138ADR2G from ON Semiconductor is a high-performance silicon-gate CMOS 1-of-8 decoder/demultiplexer. This integrated circuit decodes a three-bit address to one of eight active-low outputs. It features three chip select inputs, two active-low and one active-high, which facilitate demultiplexing, cascading, and chip-selecting functions.

 

Designed for versatility, the MC74HC138ADR2G operates over a wide voltage range of 2.0V to 6.0V. Its outputs can directly interface with CMOS, NMOS, and TTL logic levels, and it offers an output drive capability of 10 LSTTL loads. The device exhibits low input current and high noise immunity characteristic of CMOS devices.

 

This decoder/demultiplexer is supplied in a standard 16-SOIC surface mount package, measuring 0.154 inches in width. It is suitable for applications requiring efficient address decoding and data distribution. The operating temperature range is from -55°C to 125°C, making it robust for various environmental conditions.
