KK74HCT273A Datasheet, PDF (1/6 Pages) KODENSHI KOREA CORP. – Octal D Flip-Flop with Common Clock and Reset High-Performance Silicon-Gate CMOS

TECHNICAL DATA
Octal D Flip-Flop with
Common Clock and Reset
High-Performance Silicon-Gate CMOS
KK74HCT273A
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.
• TTL/NMOS Compatible Input Levels
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 4.5 to 5.5 V
• Low Input Current: 1.0 µA
