74ABT541
Octal Buffer/Line Driver with 3-STATE Outputs
General Description
The ABT541 is an octal buffer and line driver with 3-STATE
outputs designed to be employed as a memory and
address driver, clock driver, or bus-oriented transmitter/
receiver. The ABT541 is similar to the ABT244 with broad-
side pinout.
