Overview
TECHNICAL DATA 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 IN74VHC244 ORDERING INFORMATION IN74VHC244N Plastic IN74VHC244DW SOIC TA = -40° to 85° C for all packages .
