The FCT541 is designed to be employed as a memory and address driver, clock driver and bus-oriented transmitter/receiver which provides improved board density. The FCT541 is similar in function to the FCT244, except that the inputs and outputs are on opposite sides of the package. This pinout arrangement makes these devices especially useful as output ports for microprocessors and as backplane drivers, allowing ease of layout and greater board density.
