1 / 5 page SL74HC273 System Logic Semiconductor SLS 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 ORDERING INFORMATION SL74HC273N Plastic SL74HC273D SOIC TA = -55 ° to 125° C for all packages FUNCTION TABLE Inputs Output Reset Clock D Q L X X L H H H H L L H L X no change H X no change X = don’t care LOGIC DIAGRAM PIN 20=VCC PIN 10 = GND PIN ASSIGNMENT |
