74FHC244SJ

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74FHC244SJ is an octal buffer and line driver featuring three-state outputs, manufactured using advanced F-HCT CMOS technology. It provides high-speed operation comparable to equivalent Bipolar Schottky TTL while maintaining low power dissipation. The device contains eight non-inverting buffers organized into two groups of four, each with a common active-low output enable input. Designed for bus-oriented systems, it ensures signal integrity through controlled switching characteristics.
