SEMICONDUCTOR TECHNICAL DATA

The MC74VHC244 is an advanced high speed CMOS octal bus buffer

fabricated with silicon gate CMOS technology. It achieves high speed

operation similar to equivalent Bipolar Schottky TTL while maintaining

CMOS low power dissipation.

The MC74VHC244 is a noninverting 3–state buffer, and has two

active–low output enables. This device is designed to be used with 3–state

memory address drivers, etc.

The internal circuit is composed of three stages, including a buffer output

which provides high noise immunity and stable output. The inputs tolerate

voltages up to 7V, allowing the interface of 5V systems to 3V systems.
