TECHNICAL DATA KK74HC174A Hex D Flip-Flop with Common Clock and Reset High-Performance Silicon-Gate CMOS The KK74HC174A is identical in pinout to the LS/ALS174. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. This device consists of six 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 • High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION KK74HC174AN Plastic KK74HC174AD SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs PIN 16=VCC PIN 8 = GND Output Reset Clock D Q L X X L H H H H L L X no change X no change H L H X = Don’t care L = LOW voltage level H = HIGH voltage level 1 KK74HC174A MAXIMUM RATINGS* Symbol Parameter Value Unit -0.5 to +7.0 V VCC DC Supply Voltage (Referenced to GND) VIN DC Input Voltage (Referenced to GND) -1.5 to VCC +1.5 V DC Output Voltage (Referenced to GND) -0.5 to VCC +0.5 V DC Input Current, per Pin ±20 mA IOUT DC Output Current, per Pin ±25 mA ICC DC Supply Current, VCC and GND Pins ±50 mA PD Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ 750 500 mW -65 to +150 °C 260 °C VOUT IIN Tstg TL Storage Temperature Lead Temperature, 1,5 mm from Case for 4 Seconds (Plastic DIP or SOIC Package) * 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 KK74HC174A DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) VCC Symbol Parameter Test Conditions Guaranteed Limit V -55°C to 25°C ≤85 °C ≤125 °C Unit VIH Minimum HighLevel Input Voltage VOUT≥ VCC-0.1 V or ≤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= VIL or VIH ⎢IOUT⎢ ≤ 4.0 mA ⎢IOUT⎢ ≤ 5.2 mA 4.5 6.0 0.26 0.26 0.33 0.33 0.4 0.4 VIN=VIH or VIL ⎢IOUT⎢ ≤ 4.0 mA ⎢IOUT⎢ ≤ 5.2 mA VOL Maximum LowLevel Output Voltage VIN= VIL or VIH ⎢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 KK74HC174A AC ELECTRICAL CHARACTERISTICS (CL=50pF, Input tr=tf=6.0 ns, VIL= 0 V, VIH=Vcc) Guaranteed Limit VCC V -55°C to 25°C ≤85°C ≤125°C Unit Maximum Clock Frequency (50% Duty Cycle) (Figures 1 and 4) 2.0 4.5 6.0 6.0 30 35 4.8 24 28 4.0 20 24 MHz tPLH, tPHL Maximum Propagation Delay, Clock to Q (Figures 1 and 4) 2.0 4.5 6.0 110 22 19 140 28 24 165 33 28 ns tPHL Maximum Propagation Delay , Reset to Q (Figures 2 and 4) 2.0 4.5 6.0 110 21 19 140 28 24 160 32 27 ns Maximum Output Transition Time, Any Output (Figures 1 and 4) 2.0 4.5 6.0 75 15 13 95 19 16 110 22 19 ns - 10 10 10 pF Symbol fmax tTLH, tTHL CIN CPD Parameter Maximum Input Capacitance Power Dissipation Capacitance (Per Enabled Output) Typical @25°C,VCC=5.0 V Used to determine the no-load dynamic power consumption: PD=CPDVCC2f+ICCVCC 62 pF TIMING REQUIREMENTS (CL=50pF,Input tr=tf=6.0 ns, VIL= 0 V, VIH=Vcc) Guaranteed Limit VCC Symbol Parameter V -55 °C to 25°C ≤85°C ≤125°C Unit tSU Minimum Setup Time, Data to Clock (Figure 3) 2.0 4.5 6.0 50 10 9 65 13 11 75 15 13 ns th Minimum Hold Time, Clock to Data (Figure 3) 2.0 4.5 6.0 5 5 5 5 5 5 5 5 5 ns trec Minimum Recovery Time, Reset Inactive to Clock (Figure 2) 2.0 4.5 6.0 5 5 5 5 5 5 5 5 5 ns tw Minimum Pulse Width, Clock (Figure 1) 2.0 4.5 6.0 75 15 13 95 19 16 110 22 19 ns tw Minimum Pulse Width, Reset (Figure 2) 2.0 4.5 6.0 75 15 13 95 19 16 110 22 19 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 4 KK74HC174A tw tr CLOCK tf VCC 90% 50% 10% tPLH 50% 10% GND Q 1/fmax VCC 50% t PHL GND tw Q RESET 50% t PHL t rec 90% VCC CLOCK t TLH 50% GND t THL Figure 1.
