74FCT540T - Block Diagram
Description
The 74FCT540T octal buffer/line driver is similar in function to the FCT240T, 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. The 74FCT540T operates at -40C to +85C
