IN74HC273A Datasheet, PDF (1/5 Pages) Integral Corp. – OCTAL D FLIP-FLOP WITH COMMON CLOCK AND RESET

IN74HC273A
OCTAL D FLIP-FLOP WITH
COMMON CLOCK AND RESET
High-Performance Silicon-Gate CMOS
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
