KK74HC273A Datasheet, PDF (1/6 Pages) KODENSHI KOREA CORP. – Octal D Flip-Flop with Common Clock and Reset

TECHNICAL DATA
Octal D Flip-Flop with
Common Clock and Reset
High-Performance Silicon-Gate CMOS
KK74HC273A
The KK74HC273A is identical in pinout to the LS/ALS273. The
device inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LS/ALSTTL outputs.
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.
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1.0 µA
• High Noise Immunity Characteristic of CMOS Devices
