M54HC273A - Octal D Flip-Flop
MOTOROLA SEMICONDUCTOR TECHNICAL DATA Octal D Flip-Flop with Common Clock and Reset High Performance Silicon Gate CMOS The MC54/74HC273A is identical in pinout to the LS273.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
This device consists of eight D flip flops with common Clock and Reset inputs.
Each flip flop is loaded with a low to high transition of the Clock input
