74F2244 Overview

Octal buffer with 30ohm equivalent output termination 3-State

74F2244 Octal Buffer/Line Driver with 25Ω Series Resistors in Outputs
October 1988
Revised March 1999
74F2244
Octal Buffer/Line Driver
with 25Ω Series Resistors in Outputs
General Description
The F2244 is an octal buffer/line driver designed to drive
the capacitive inputs of MOS memory drivers, address driv-
ers, clock drivers and bus-oriented transmitters/receivers.
The 25Ω series resistors in the outputs reduce ringing and
eliminate the need for external resistors.
Features

s
25Ω series resistors in outputs eliminate the need for
external resistors.
s
Designed to drive the capacitive inputs of MOS devices
