描述 Description

Octal D Flip-Flop with Common Clock and Reset with LSTTL-Compatible Inputs
High–Performance Silicon–Gate CMOSThe 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.
