IN74AC273

TECHNICAL DATA IN74AC273 Octal D Flip-Flop with Common Clock and Reset The IN74AC273 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 ORDERING INFORMATION IN74AC273N Plastic IN74AC273DW SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs PIN 20=VCC PIN 10 = GND Reset L H H H H X = don’t care L Clock X D X H L X X Output Q L H L no change no change w w w .d h s a t a ee . u t4 m o c 1 www.DataSheet4U.com IN74AC273 MAXIMUM RATINGS* Symbol VCC VIN VOUT IIN IOUT ICC PD Tstg TL * Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Output Voltage (Referenced to GND) DC Input Current, per Pin DC Output Sink/Source Current, per Pin DC Supply Current, VCC and GND Pins Power Dissipation in Still Air, Plastic DIP** SOIC Package** Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) Value -0.5 to +7.0 -0.5 to VCC +0.5 -0.5 ...
