The IN74ACT273 is identical in pinout to the LS/ALS273, HC/HCT273. The IN74ACT273 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs.

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.
