Octal Buffer/Line Driver with 25X 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 25X series resistors in the outputs reduce ringing and
eliminate the need for external resistors.
