IK Semicon IN74VHCT74D Dual d flip-flop with set and reset Datasheet

TECHNICAL DATA
Dual D Flip-Flop with Set and Reset
IN74VHCT74 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, IN74VHCT74 can be compared
with equivalent bipolar ICs based on Schottky TTL and two
times surpasses ICs of IN74НС series.
IN74VHCT74 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 IN74VHCT74 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 IN74VHCT74 are compatible with TTL level
and output levels with CMOS levels.
