SL74HCT273

SL74HCT273 Octal D Flip-Flop with Common Clock and Reset High-Performance Silicon-Gate CMOS The SL74HCT273 is identical in pinout to the LS/ALS273. The SL74HCT273 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 SL74HCT273N Plastic SL74HCT273D SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE PIN 20=VCC PIN 10 = GND Reset L H H H H X = don’t care L Inputs Clock X D X H L X X Output Q L H L no change no change SLS System Logic Semiconductor SL74HCT273 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 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 -1.5 to VCC +1.5 -0.5 to VCC +0.5 ±20 ±35 ±75 750 500 -65 to +150 260 Unit V V V mA mA mA mW °C °C Maximum Ratings are those value...
