MC74VHC74
Dual D-Type Flip-Flop
with Set and Reset
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.
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 7.0 V, allowing the interface of 5.0 V systems to 3.0 V systems.
