SEMICONDUCTOR TECHNICAL DATA  
The MC74VHCT74A is an advanced high speed CMOS D–type flip–flop  
fabricated with silicon gate CMOS technology. It achieves high speed  
operation similar to equivalent Bipolar Schottky TTL while maintaining  
CMOS low power dissipation.  
The signal level applied to the D input is transferred to Q output during the  
positive going transition of the Clock pulse.  
D SUFFIX  
14–LEAD SOIC PACKAGE  
CASE 751A–03  
Reset (RD) and Set (SD) are independent of the Clock (CP) and are  
accomplished by setting the appropriate input Low.  
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.  
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.  
DT SUFFIX  
14–LEAD TSSOP PACKAGE  
CASE 948G–01  
The VHCT74A input structures provide protection when voltages between  
0V and 5.5V are applied, regardless of the supply voltage. The output  
structures also provide protection when VCC=0V. These input and output  
structures help prevent device destruction caused by supply voltage –  
input/output voltage mismatch, battery backup, hot insertion, etc.
