SL74HC273
Octal D Flip-Flop with Common Clock and Reset
High-Performance Silicon-Gate CMOS
The SL74HC273 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
