The MC74HC541A is identical in pinout to the LS541. The device  
inputs are compatible with Standard CMOS outputs. External pullup  
resistors make them compatible with LSTTL outputs.  
The HC541A is an octal non–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.
