Octal 3-State Inverting Buffer/Line Driver/Line Receiver High-Speed Silicon-Gate CMOS

The IN74AC240 is identical in pinout to the LS/ALS240, HC/HCT240. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.
This octal inverting buffer/line driver/line receiver is designed to be used with 3-state memory address drivers, clock drivers, and other bus-oriented systems. The device has inverting outputs and two active-low output enables.
