TECHNICAL DATA KK74HC75A Dual 2-Bit Transparent Latch High-Performance Silicon-Gate CMOS The KK74HC75A is identical in pinout to the LS/ALS75. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. This device consists of two independent 2-bit transparent latches and can be used as temporary storage for binary information between processing units and input/output or indicator units. Each latch stores the input data while Latch Enable is at a logic low. The outputs follow the data inputs when Latch Enable is at a logic high. • 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 KK74HC75AN Plastic KK74HC75AD SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM PIN 5=VCC PIN 12 = GND FUNCTION TABLE Inputs Outputs D Latch Enable Q Q L H L H H H H L X L Q0 Q0 X = Don’t Care Q0 = latched data 1 KK74HC75A 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 mm from Case for 10 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 KK74HC75A 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 0.3 0.9 1.2 0.3 0.9 1.2 0.3 0.9 1.2 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 80 µA 3 KK74HC75A AC ELECTRICAL CHARACTERISTICS (CL=50pF,Input tr=tf=6.0 ns) Guaranteed Limit VCC Symbol Parameter V 25 °C to -55°C ≤85°C ≤125°C Unit tPLH, tPHL Maximum Propagation Delay, D to Q (Figures 1 and 5) 2.0 4.5 6.0 125 25 21 155 31 26 190 38 32 ns tPLH, tPHL Maximum Propagation Delay , D to Q (Figures 1 and 5) 2.0 4.5 6.0 110 22 19 140 28 24 165 33 28 ns tPLH, tPHL Maximum Propagation Delay ,Latch Enable to Q (Figures 2 and 5) 2.0 4.5 6.0 145 29 25 180 36 31 220 44 38 ns tPLH, tPHL Maximum Propagation Delay ,Latch Enable to Q (Figures 2 and 5) 2.0 4.5 6.0 125 25 21 155 31 26 190 38 32 ns tTLH, tTHL Maximum Output Transition Time, Any Output (Figures 3 and 5) 2.0 4.5 6.0 75 15 13 95 19 16 110 22 19 ns - 10 10 10 pF CIN Maximum Input Capacitance Power Dissipation Capacitance (Per Latch) CPD Typical @25°C,VCC=5.0 V Used to determine the no-load dynamic power consumption: PD=CPDVCC2f+ICCVCC 35 pF 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, Input D to Latch Enable (Figure 4) 2.0 4.5 6.0 100 20 17 125 25 21 150 30 26 ns th Minimum Hold Time,Latch Enable to D (Figure 4) 2.0 4.5 6.0 25 5 5 30 6 6 40 8 7 ns tw Minimum Pulse Width, Latch Enable Input (Figure 2) 2.0 4.5 6.0 80 16 14 100 20 17 120 24 20 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 KK74HC75A Figure 1.
