Octal D Flip-Flop with Common Clock and Reset High-Performance Silicon-Gate CMOS

IK Semicon Co., Ltd 

TECHNICAL DATA

Octal D Flip-Flop with

Common Clock and Reset

High-Performance Silicon-Gate CMOS

IN74HC273A

The IN74HC273A 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
