TECHNICAL DATA KK74ACT374 Octal 3-State Noninverting D Flip-Flop High-Speed Silicon-Gate CMOS The KK74ACT374 is identical in pinout to the LS/ALS374, HC/HCT374. The KK74ACT374 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. Data meeting the setup and hold time is clocked to the outputs with the rising edge of the Clock. The Output Enable input does not affect the states of the flip-flops, but when Output Enable is high, the outputs are forced to the high-impedance state; thus, data may be stored even when the outputs are not enabled. • 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 KK74ACT374N Plastic KK74ACT374DW SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Output Enable PIN 20=VCC PIN 10 = GND D Q L H H L L L X no change X Z L H Clock Output L,H, X X = don’t care Z = high impedance 1 KK74ACT374 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) -0.5 to VCC +0.5 V DC Output Voltage (Referenced to GND) -0.5 to VCC +0.5 V DC Input Current, per Pin ±20 mA IOUT DC Output Sink/Source Current, per Pin ±50 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 KK74ACT374 DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) VCC Symbol Parameter Test Conditions Guaranteed Limits V 25 °C -40°C to 85°C Unit VIH Minimum HighLevel Input Voltage VOUT=0.1 V or VCC-0.1 V 4.5 5.5 2.0 2.0 2.0 2.0 V VIL Maximum Low Level Input Voltage VOUT= 0.1 V or VCC-0.1 V 4.5 5.5 0.8 0.8 0.8 0.8 V VOH Minimum HighLevel Output Voltage IOUT ≤ -50 µA 4.5 5.5 4.4 5.4 4.4 5.4 V 4.5 5.5 3.86 4.86 3.76 4.76 4.5 5.5 0.1 0.1 0.1 0.1 VIN= VIH or VIL IOL=24 mA IOL=24 mA 4.5 5.5 0.36 0.36 0.44 0.44 * VIN= VIH or VIL IOH=-24 mA IOH=-24 mA VOL Maximum LowLevel Output Voltage IOUT ≤ 50 µA V * IIN Maximum Input Leakage Current VIN=VCC or GND 5.5 ±0.1 ±1.0 µA IOZ Maximum ThreeState Leakage Current VIN (OE)=VIL, VIH VIN=VCC, GND VOUT=VCC, GND 5.5 ±0.5 ±5.0 µA ∆ICCT Additional Max ICC/Input VIN=VCC - 2.1 V 5.5 1.5 mA IOLD +Minimum Dynamic Output Current VOLD=1.65 V Max 5.5 75 mA IOHD +Minimum Dynamic Output Current VOHD=3.85 V Min 5.5 -75 mA ICC Maximum Quiescent Supply Current (per Package) VIN=VCC or GND 5.5 80 µA 8.0 * All outputs loaded; thresholds on input associated with output under test. +Maximum test duration 2.0 ms, one output loaded at a time. 3 KK74ACT374 AC ELECTRICAL CHARACTERISTICS (VCC=5.0 V ± 10%, CL=50pF,Input tr=tf=3.0 ns) Guaranteed Limits Symbol Parameter 25 °C Min Max -40°C to 85°C Min Unit Max fmax Maximum Clock Frequency (Figure 1) 100 90 tPLH Propagation Delay, Clock to Q (Figure 1) 2.0 10 2.0 11.5 ns tPHL Propagation Delay, Clock to Q (Figure 1) 2.0 9.5 1.5 11 ns tPZH Propagation Delay, Output Enable to Q (Figure 2) 2.0 9.5 1.5 10.5 ns tPZL Propagation Delay, Output Enable to Q (Figure 2) 1.5 9.0 1.5 10.5 ns tPHZ Propagation Delay, Output Enable to Q (Figure 2) 1.5 11.5 1.0 12.5 ns tPLZ Propagation Delay, Output Enable to Q (Figure 2) 1.5 8.5 1.0 10 ns CIN Maximum Input Capacitance 4.5 MHz 4.5 pF Typical @25°C,VCC=5.0 V CPD Power Dissipation Capacitance 80 pF TIMING REQUIREMENTS (VCC=5.0 V ± 10%,(CL=50pF, Input tr=tf=3.0 ns) Guaranteed Limits Symbol Parameter 25 °C -40°C to 85°C Unit tsu Minimum Setup Time,Data to Clock (Figure 3) 5.0 5.5 ns th Minimum Hold Time, Clock to Data (Figure 3) 1.5 1.5 ns tw Minimum Pulse Width, Clock (Figure 1) 5.0 5.0 ns 4 KK74ACT374 Figure 1.
