Octal D Flip-Flop with Common Clock and Reset with LSTTL-Compatible Inputs

High?Performance Silicon?Gate CMOS

The MC74HCT273A may be used as a level converter for interfacing TTL or NMOS outputs to High?Speed CMOS inputs. The HCT273A is identical in pinout to the LS273.

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.
