High-Performance Silicon-Gate CMOS The MC74HC273A 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. Reset is asynchronous and active low.
