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.
