No Preview Available ! Octal D Flip-Flop with Common Clock and Reset TECHNICAL DATA IN74AC273 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 LOGIC DIAGRAM PIN ASSIGNMENT PIN 20=VCC PIN 10 = GND www.datasheet4u.com FUNCTION TABLE Inputs Reset Clock LX H H HL H X = don’t care D X H L X X Output Q L H L no change no change 1 1 page IN74AC273 Figure 1.
