High−Performance Silicon−Gate CMOS The MC74HC377A 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
Enable (E) inputs. Each flip−flop is loaded with a low−to−high transition of the Clock input. Enable (E) is active low.
