Product Summary

The 74HC540A is an octal inverting buffer/line driver/line receiver designed to be used with 3-state memory address drivers, clock drivers, and other bus-oriented systems. The 74HC540A is identical in pinout to the LS540. The device inputs are compatible with Standard CMOS outputs. External pull-up resistors make them compatible with LSTTL outputs. This device features inputs and outputs on opposite sides of the package and two ANDed active.low output enables.
