ON Semiconductor MM74HC138MTCX Decoder/Demultiplexer

The MM74HC138MTCX is a high-performance, CMOS 3-to-8 line decoder/demultiplexer manufactured by ON Semiconductor. This integrated circuit is designed to facilitate the implementation of multiplexing and demultiplexing functions in a variety of digital applications. It is particularly well-suited for systems that require the conversion of a binary input to a uniquely selected output, making it ideal for memory chip selection, data routing, and control signal decoding.

The MM74HC138MTCX features three binary select inputs (A, B, and C), an enable input, and eight mutually exclusive outputs. The device operates with a supply voltage ranging from 2V to 6V, accommodating a broad spectrum of logic levels and making it compatible with most TTL, CMOS, and low-voltage systems. Its low quiescent current consumption ensures minimal power drain when the device is in standby mode, contributing to energy-efficient designs.

ON Semiconductor's commitment to quality is evident in the MM74HC138MTCX, which is built to provide high noise immunity and low power dissipation. The chip's balanced propagation delay and transition times offer reliable and predictable performance across its operational temperature range. This makes it a reliable choice for critical applications in consumer electronics, telecommunications, and computing where precise timing and signal integrity are paramount.

Encased in a TSSOP-16 package, the MM74HC138MTCX is designed for surface-mount technology (SMT), offering a compact footprint for space-constrained applications. This packaging allows for efficient utilization of PCB real estate, facilitating higher density designs without compromising performance. Its robust construction ensures durability and resistance to the rigors of automated assembly processes.

Whether you're designing a complex microprocessor system or a simple peripheral interface, the MM74HC138MTCX provides a versatile and reliable solution for your decoding and demultiplexing needs. With ON Semiconductor's reputation for producing high-quality semiconductor components, you can integrate the MM74HC138MTCX into your design with confidence.
