No Preview Available ! TECHNICAL DATA Octal D Flip-Flop with Common Clock and Reset High-Performance Silicon-Gate CMOS IN74HCT273A The IN74HCT273A is identical in pinout to the LS/ALS273. The IN74HCT273A 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 ORDERING INFORMATION IN74HCT273AN Plastic IN74HCT273ADW SOIC TA = -55° to 125° 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 IN74HCT273A Figure 1.
