KK74ACT273N

TECHNICAL DATA KK74ACT273 Octal D Flip-Flop with Common Clock and Reset High-Speed Silicon-Gate CMOS The KK74ACT273 is identical in pinout to the LS/ALS273, HC/HCT273. The KK74ACT273 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 KK74ACT273N Plastic KK74ACT273DW SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Reset L PIN 20=VCC PIN 10 = GND 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 1 KK74ACT273 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 to VCC +0.5 ±20 ±50 ±50 750 500 -65 to +150 260 Unit V V V mA mA mA mW °C °C Maximum Ratings are those values beyond which damage to the device may occur.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open. 2 KK74ACT273 DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) VCC Symbol VIH VIL VOH Parameter Minimum HighLevel Input Voltage Maximum Low Level Input Voltage Minimum HighLevel Output Voltage Test Conditions VOUT=0.1 V or VCC-0.1 V VOUT=0.1 V or VCC-0.1 V IOUT ≤ -50 µA VIN=VIH or VIL IOH=-24 mA IOH=-24 mA VOL Maximum LowLevel Output Voltage IOUT ≤ 50 µA * * Guaranteed Limits 2 5 °C 2.0 2.0 0.8 0.8 4.4 5.4 3.86 4.86 0.1 0.1 0.36 0.36 ±0.1 -40°C to 8 5 °C 2.0 2.0 0.8 0.8 4.4 5.4 3.76 4.76 0.1 0.1 0.44 0.44 ±1.0 1.5 75 -75 8.0 80 µA mA mA mA µA V Unit V V V V 4.5 5.5 4.5 5.5 4.5 5.5 4.5 5.5 4.5 5.5 4.5 5.5 5.5 5.5 5.5 5.5 5.5 VIN=VIH or VIL IOL=24 mA IOL=24 mA VIN=VCC or GND VIN=VCC - 2.1 V VOLD=1.65 V Max VOHD=3.85 V Min VIN=VCC or GND IIN ∆ICCT IOLD IOHD ICC Maximum Input Leakage Current Additional Max ICC/Input +Minimum Dynamic Output Current +Minimum Dynamic Output Current Maximum Quiescent Supply Current (per Package) * All outputs loaded; thresholds on input associated with output under test. +Maximum test duration 2.0 ms, one output loaded at a time. 3 KK74ACT273 AC ELECTRICAL CHARACTERISTICS (VCC=5.0 V ± 10%, CL=50pF,Input tr=tf=3.0 ns) Guaranteed Limits Symbol fmax tPHL tPLH tPHL CIN Parameter Maximum Clock Frequency (Figure 1) Propagation Delay, Clock to Q (Figure 1) Propagation Delay, Clock to Q (Figure 1) Propagation Delay, Reset to Q (Figure 2) Maximum Input Capacitance 2 5 °C Min 125 3.0 3.0 3.0 4.5 10.0 11.0 11.0 Max -40°C to 85°C Min 125 2.5 2.5 2.5 4.5 11.0 12.0 11.5 Max MHz ns ns ns pF Unit Typical @25°C,VCC=5.0 V CPD Power Dissipation Capacitance 50 pF TIMING REQUIREMENTS (VCC=5.0 V ± 10%, CL=50pF, Input tr=tf=3.0 ns) Guaranteed Limits Symbol tsu th tw tw trec Parameter Minimum Setup Time, Data to Clock (Figure 3) Minimum Hold Time, Data to Clock (Figure 3) Minimum Pulse Width, Clock (Figure 1) Minimum Pulse Width, Reset (Figure 2) Minimum Recovery Time, Reset to Clock (Figure 2) 2 5 °C 4.5 2.0 4.0 4.0 2.0 -40°C to 8 5 °C 5.5 2.0 4.5 4.5 3.0 Unit ns ns ns ns 4 KK74ACT273 Figure 1.
