TECHNICAL DATA

IN74VHC244

Octal Buffer /Line Driver NINV (3-state)

IN74VHC244 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, IN74VHC244 can be compared

with equivalent bipolar ICs based on Schottky TTL and two

times surpasses ICs of IN74НС series.

IN74VHC244 tolerates operation under conditions when

voltage on input is exceeded up to 7V without affecting

characteristics and IC reliability. This possibility allows to

use IN74VHC244 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 IN74VHC244D are compatible

with CMOS levels
