74HC138D,653 3-to-8 Line Decoder/Demultiplexer Inverting IC | High-Speed CMOS | SOIC-16 SMD

Description

The 74HC138D,653 is a high-speed 3-to-8 Line Decoder/Demultiplexer designed for decoding, demultiplexing, and memory-addressing applications. It accepts three binary weighted address inputs (A0, A1, A2) and, when enabled, provides eight mutually exclusive active-LOW outputs. This device features three enable inputs—two active-LOW (E1, E2) and one active-HIGH (E3)—which simplify cascading or expansion for larger decoder configurations.

Built using advanced silicon-gate CMOS technology, this IC combines the high-speed operation of standard Schottky TTL with the low power consumption and high noise immunity of the HC logic family. The 74HC138D is a critical component for high-performance memory decoding and data routing in embedded systems and industrial control applications. The SOIC-16 surface-mount package is optimized for efficient PCB layout and reliable automated assembly.
