SEMICONDUCTOR TECHNICAL DATA  
The MC74VHC74 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.
