ON Semiconductort  
Octal Bus Buffer/Line Driver  
with 3-State Outputs  
MC74VHCT244A  
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.  
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.  
DW SUFFIX  
20–LEAD SOIC WIDE PACKAGE  
CASE 751D–05  
The VHCT inputs are compatible with TTL levels. This device can  
be used as a level converter for interfacing 3.3V to 5.0V, because it has  
full 5V CMOS level output swings.  
The VHCT244A input and output (when disabled) structures  
provide protection when voltages between 0V and 5.5V 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.
