Octal D Flip−Flop with Common Clock and Reset

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.
