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 IN74 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.
