TECHNICAL DATA

Octal Buffer /Line Driver NINV (3-state)

KK74VHCT244

KK74VHCT244 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, KK74VHCT244 can be compared

with equivalent bipolar ICs based on Schottky TTL and two

times surpasses ICs of KK74НС series.

KK74VHCT244 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 KK74VHCT244 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.

ORDERING INFORMATION
