SEMICONDUCTOR TECHNICAL DATA  
The MC74VHCT374A is an advanced high speed CMOS octal flip–flop  
with 3–state output fabricated with silicon gate CMOS technology. It  
achieves high speed operation similar to equivalent Bipolar Schottky TTL  
while maintaining CMOS low power dissipation.  
This 8–bit D–type flip–flop is controlled by a clock input and an output  
enable input. When the output enable input is high, the eight outputs are in a  
high impedance state.  
DW SUFFIX  
20–LEAD SOIC PACKAGE  
CASE 751D–04  
The internal circuit is composed of three stages, including a buffer output  
which provides high noise immunity and stable output.  
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 VHCT374A 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.
