74FCT2244T

Octal Buffer/Line Driver

The 74FCT2244T Octal Buffer/Line Driver is designed to be employed as a memory and address driver, clock driver, and bus-oriented transmitter/receiver which provides improved board density. The octal buffer has balanced output drive with current limiting resistors, reducing the need for external series terminating resistors. The 74FCT2244T octal buffer operates across Industrial temp range (-40C to +85C) and is a plug-in replacement for the74FCT244T.
