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 flipflops with common Clock and Reset inputs. Each flipflop is loaded with a lowtohigh transition of the Clock input. Reset is asynchronous and active low.
