TECHNICAL DATA
KK74HCT273A
Octal D Flip-Flop with
Common Clock and Reset
High-Performance Silicon-Gate CMOS
The KK74HCT273A is identical in pinout to the LS/ALS273.
The KK74HCT273A 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.
