KK74AC273 Datasheet, PDF (1/6 Pages) KODENSHI KOREA CORP. – Octal D Flip-Flop with Common Clock and Reset

Octal D Flip-Flop with
Common Clock and Reset
TECHNICAL DATA
KK74AC273
The KK74AC273 is identical in pinout to the LS/ALS273,
HC/HCT273. The device inputs are compatible with standard CMOS
outputs; with pullup resistors, they are compatible with LS/ALS 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; 0.1 µA @ 25°C
• High Noise Immunity Characteristic of CMOS Devices
• Outputs Source/Sink 24 mA
