IN74VHC02
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
