KK74VHCT74

Dual D Flip-Flop with Set and Reset

KK74VHCT74 is high-speed logic IC made by CMOS

technology and designed for use in high-performance

calculating systems with a wide supply voltage range.

As for operation speed, KK74VHCT74 can be compared

with equivalent bipolar ICs based on Schottky TTL and two

times surpasses ICs of KK74НС series.

KK74VHCT74 tolerates operation under conditions when

voltage on input & output is exceeded up to 7V without

affecting characteristics and IC reliability. This possibility

allows to use KK74VHCT74 in radio-electronic devices for

interfacing with supply voltages 5V and 3V, eliminate IC

failure under supply voltage source emergency outage.

Use of output edge shaping block in the microcircuit

allows to reduce noise amplitude of noises when switching

outputs into the same state simultaneously.

Input levels of KK74VHCT74 are compatible with TTL level

and output levels with CMOS levels.
