74ABT2541
Octal Buffer/Line Driver with
25鈩?Series Resistors in the Outputs
General Description
The ABT2541 is an octal buffer and line driver designed to
drive the capacitive inputs of MOS memory drivers,
address drivers, clock drivers, and bus-oriented transmit-
ters/receivers. Functionally identical to the ABT541.
The 25鈩?series resistors in the outputs reduce ringing and
eliminate the need for external resistors.
