TECHNICAL DATA
Octal Buffer /Line Driver NINV (3-state)
IN74VHCT244 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, IN74VHCT244 can be compared
with equivalent bipolar ICs based on Schottky TTL and two
times surpasses ICs of IN74袧小 series.
IN74VHCT244 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 IN74VHCT244 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 IN74VHCT244 are compatible with TTL
level and output levels with CMOS levels.
