IN74ACT273

TECHNICAL DATA IN74ACT273 Octal D Flip-Flop with Common Clock and Reset High-Speed Silicon-Gate CMOS The IN74ACT273 is identical in pinout to the LS/ALS273, HC/HCT273. The IN74ACT273 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. 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. TTL/NMOS Compatible Input Levels Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 4.5 to 5.5 V Low Input Current: 1.0 µA; 0.1 µA @ 25°C Outputs Source/Sink 24 mA ORDERING INFORMATION IN74ACT273N Plastic IN74ACT273DW SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Reset L Clock X D X H L 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 PIN 20=VCC PIN 10 = GND H H H H X = don’t care 1 www.DataSheet4U.com IN74ACT273 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...
