54FCT540 Datasheet | National Semiconductor

Description The ’FCT540 is an octal buffer/line drivers designed to be employed as memory and address drivers, clock drivers and bus oriented transmitter/receivers. These devices are similar in function to the ’FCT240 while providing flow-through architecture (inputs on opposite side from outputs). This pinout arrangement makes these devices especially useful as output ports for microprocessors, allowing ease of layout and greater PC board density. Features n TRI-STATE inverting outputs n Inputs and outputs opposite side of package, allowing easier interface to microprocessors n TTL input and output level patible n CMOS power consumption n Output sink capability of 48m A, source capability of 12 m A n Standard Microcircuit Drawing (SMD) 5962-8976701 Logic Symbol IEEE/IEC Connection Diagrams Pin Assignment for DIP and Flatpak Inputs OE1 L OE2 L H XX X HX L LL H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial Z = High Impedance DS100970-1 Outputs DS100970-3 Pin Assignment for LCC DS100970-2 TRI-STATE® is a registered trademark of National Semiconductor Corporation.
