The 74HC541 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 74HC541 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.
The 74HC541 is similar in function to the HC540A, which has inverting outputs.
