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.

*Both outputs will remain high as long as Set and Re-

set are low, but the output states are unpredictable

if Set and Reset go high simultaneously.
