Part Number 74VHC244
Description Octal Buffer/Line Driver
Feature 74VHC244 Octal Buffer/Line Driver with 3 -STATE Outputs November 1992 Revised A pril 2005 74VHC244 Octal Buffer/Line D river with 3-STATE Outputs General Des cription The VHC244 is an advanced high speed CMOS octal bus buffer fabricated with silicon gate CMOS technology.
It achieves high speed operation similar t o equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipa tion.
The VHC244 is a non-inverting 3-S TATE buffer having two active-LOW outpu t enables.
These devices are designed t o be used as 3-STATE memory address dri vers, clock drivers, and bus oriented t ransmitter/rec .

Part Number 74VHC244
Description Octal buffer/line driver
Feature 74VHC244; 74VHCT244 Octal buffer/line d river; 3-state Rev.
01 — 17 August 20 09 Product data sheet 1.
General desc ription The 74VHC244; 74VHCT244 are a h igh-speed Si-gate CMOS devices.
The 74V HC244; 74VHCT244 have octal non-inverti ng buffer/line drivers with 3-state out puts.
The 3-state outputs are controlle d by the output enable inputs (nOE).
A HIGH on nOE causes the outputs to assum e a high-impedance OFF-state.
