TECHNICAL DATA
Quad 2-Input NOR Gate
IN74VHC02 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, IN74VHC02 can be compared with equivalent bipolar ICs based on Schottky TTL and two times surpasses ICs of IN74 series. IN74VHC02 tolerates operation under conditions when voltage on input is exceeded up to 7V without affecting characteristics and IC reliability. This possibility allows to use IN74VHC02 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 and output levels of IN74VHC02 are compatible with CMOS levels
