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 KK74HC163A DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) VCC Symbol Parameter Test Conditions Guaranteed Limit V 25 °C to -55°C ≤85 °C ≤125 °C Unit VIH Minimum HighLevel Input Voltage VOUT=0.1 V or VCC-0.1 V ⎢IOUT⎢≤ 20 µA 2.0 4.5 6.0 1.5 3.15 4.2 1.5 3.15 4.2 1.5 3.15 4.2 V VIL Maximum Low Level Input Voltage VOUT=0.1 V or VCC-0.1 V ⎢IOUT⎢ ≤ 20 µA 2.0 4.5 6.0 0.5 1.35 1.8 0.5 1.35 1.8 0.5 1.35 1.8 V VOH Minimum HighLevel Output Voltage VIN=VIH or VIL ⎢IOUT⎢ ≤ 20 µA 2.0 4.5 6.0 1.9 4.4 5.9 1.9 4.4 5.9 1.9 4.4 5.9 V 4.5 6.0 3.98 5.48 3.84 5.34 3.7 5.2 2.0 4.5 6.0 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 VIN=VIH or VIL ⎢IOUT⎢ ≤ 6.0 mA ⎢IOUT⎢ ≤ 7.8 mA 4.5 6.0 0.26 0.26 0.33 0.33 0.4 0.4 VIN=VIH or VIL ⎢IOUT⎢ ≤ 6.0 mA ⎢IOUT⎢ ≤ 7.8 mA VOL Maximum LowLevel Output Voltage VIN=VIH or VIL ⎢IOUT⎢ ≤ 20 µA V IIN Maximum Input Leakage Current VIN=VCC or GND 6.0 ±0.1 ±1.0 ±1.0 µA ICC Maximum Quiescent Supply Current (per Package) VIN=VCC or GND IOUT=0µA 6.0 4.0 40 160 µA 3 KK74HC163A AC ELECTRICAL CHARACTERISTICS (CL=50pF,Input tr=tf=6.0 ns) Guaranteed Limit VCC V 25 °C to -55°C ≤85°C ≤125°C Unit 2.0 4.5 6.0 6 30 35 5 24 28 4 20 24 MHz 2.0 4.5 6.0 120 20 16 160 23 20 200 28 22 ns 2.0 4.5 6.0 145 22 18 185 25 20 320 30 23 ns 2.0 4.5 6.0 110 16 14 150 18 15 190 20 17 ns 2.0 4.5 6.0 135 18 15 175 20 16 210 22 20 ns 2.0 4.5 6.0 120 22 18 160 27 22 200 30 25 ns Carry Out (Figures 1,6) 2.0 4.5 6.0 145 22 20 185 28 24 220 35 28 ns Maximum Output Transition Time, Any Output, (Figures 1 and 6) 2.0 4.5 6.0 75 15 13 95 19 16 110 22 19 ns - 10 10 10 pF Symbol fmax Parameter Maximum Clock Frequency (Figures1,6) tPLH Maximum Propagation Delay Clock to Q tPHL (Figures 1,6) tPLH Maximum Propagation Delay Enable T to Ripple Carry Out tPHL (Figures 2,6) tPLH Maximum Propagation Delay Clock to Ripple tPHL tTLH, tTHL CIN Maximum Input Capacitance Power Dissipation Capacitance (Per Gate) CPD Used to determine the no-load dynamic power consumption: PD=CPDVCC2f+ICCVCC Typical @25°C,VCC=5.0 V 30 pF 4 KK74HC163A TIMING REQUIREMENTS (CL=50pF,Input tr=tf=6.0 ns) Guaranteed Limit VCC Symbol Parameter V 25 °C to -55°C ≤85°C ≤125°C Unit tsu Minimum Setup Time, Preset Data Inputs to Clock (Figure 4) 2.0 4.5 6.0 40 15 12 60 20 18 80 30 20 ns tsu Minimum Setup Time, Load to Clock (Figure 4) 2.0 4.5 6.0 60 15 12 75 20 18 90 30 20 ns tsu Minimum Setup Time, Reset to Clock (Figure 3) 2.0 4.5 6.0 60 20 17 75 25 23 90 35 25 ns tsu Minimum Setup Time, Enable T or Enable P to Clock (Figure 5) 2.0 4.5 6.0 80 20 17 95 25 23 110 35 25 ns th Minimum Hold Time, Clock to Load or Preset Data Inputs (Figure 4) 2.0 4.5 6.0 3 3 3 3 3 3 3 3 3 ns th Minimum Hold Time, Clock to Reset (Figure 3) 2.0 4.5 6.0 3 3 3 3 3 3 3 3 3 ns th Minimum Hold Time, Clock to Enable T or Enable P (Figure 5) 2.0 4.5 6.0 3 3 3 3 3 3 3 3 3 ns trec Minimum Recovery Time, Load Inactive to Clock (Figure 4) 2.0 4.5 6.0 80 15 12 95 20 17 110 26 23 ns tw Minimum Pulse Width, Clock (Figure 1) 2.0 4.5 6.0 60 12 10 75 15 13 90 18 15 ns tw Minimum Pulse Width, Reset (Figure 3) 2.0 4.5 6.0 60 12 10 75 15 13 90 18 15 ns tr, tf Maximum Input Rise and Fall Times (Figure 1) 2.0 4.5 6.0 1000 500 400 1000 500 400 1000 500 400 ns 5 KK74HC163A Figure 1.

Test Circuit 6 KK74HC163A VCC=Pin 16 GND=Pin 8 The flip-flops shown in the circuit diagrams are Toggle-Enable flip-flops. A Toggle-Enable flip-flop is a combination of a D flip-flop and a T flip-flop. When loading data from Preset inputs P0, P1, P2, and P3, the Load signal is used to disable the Toggle input (Tn) of the flip-flop. The logic level at the Pn input is then clocked to the Q output of the flip-flop on the next rising edge of the clock. A logic zero on the Reset device input forces the internal clock (C) high and resets the Q output of the flip-flop low.

Actual performance will depend on number of stages. This limitation is due to set up times between Enable (Port) and clock. Figure 9. N-Bit Synchronous Counters Figure 10.
