SEMICONDUCTOR TECHNICAL DATA  
High–Performance Silicon–Gate CMOS  
The MC74HC540A is identical in pinout to the LS540. The device inputs  
are compatible with Standard CMOS outputs. External pullup resistors make  
them compatible with LSTTL outputs.

The HC540A 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. This device features inputs and outputs on opposite  
sides of the package and two ANDed active–low output enables.  
The HC540A is similar in function to the HC541A, which has non–inverting  
outputs.
