MC74VHCT244A

Octal Bus Buffer/Line Driver

with 3-State Outputs

The MC74VHCT244A 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.

http://onsemi.com

The MC74VHCT244A 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 VHCT inputs are compatible with TTL levels. This device can

be used as a level converter for interfacing 3.3 V to 5.0 V, because it

has full 5.0 V CMOS level output swings.

The VHCT244A input and output (when disabled) structures

provide protection when voltages between 0 V and 5.5 V are applied,

regardless of the supply voltage. These input and output structures

help prevent device destruction caused by supply

voltage−input/output voltage mismatch, battery backup, hot insertion,

etc.
