54FCT541
Octal Buffer/Line Driver with TRI-STATE^® Outputs
General Description
The ’FCT541 is an octal buffer and line driver with
TRI-STATE outputs designed to be employed as a memory
and address driver, clock driver, or bus-oriented transmitter/
receiver. The ’FCT541 is similar to the ’FCT244 with broad-
side pinout.
