| TECHNICAL DATA Hex Schmitt-Trigger Inverter High-Speed Silicon-Gate CMOS The KK74ACT14 is identical in pinout to the LS/ALS14, HC/HCT14. The KK74ACT14 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The KK74ACT14 is useful to "square up" slow input rise and fall times. Due to the hysteresis voltage of the Schmitt trigger, the KK74ACT14 finds applications in noisy environments. * 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 A; 0.1 A @ 25C * Outputs Source/Sink 24 mA KK74ACT14 ORDERING INFORMATION KK74ACT14N Plastic KK74ACT14D SOIC TA = -40 to 85 C for all packages LOGIC DIAGRAM PIN ASSIGNMENT FUNCTION TABLE Inputs A L H PIN 14 =VCC PIN 7 = GND Output Y H L 1 KK74ACT14 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 KK74ACT14 DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) VCC Symbol VOH Parameter Minimum High-Level Output Voltage Test Conditions IOUT -50 A VIN VT - min IOH=-12 mA IOH=-24 mA IOH=-24 mA * Guaranteed Limits 25 C 4.4 5.4 3.86 4.86 0.1 0.1 0.36 0.36 2.0 2.0 0.8 0.8 1.2 1.2 0.4 0.4 0.1 1.0 1.5 75 -75 4.0 40 -40C to 85C 4.4 5.4 3.76 4.76 0.1 0.1 0.44 0.44 V V Unit 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 4.5 5.5 4.5 5.5 5.5 5.5 5.5 5.5 5.5 VOL Maximum Low-Level Output Voltage IOUT 50 A * VIN= VT +max IOL=12 mA IOL=24 mA IOL=24 mA VT +max Maximum PositiveGoing Input Threshold Voltage Minimum NegativeGoing Input Threshold Voltage Maximum Hysteresis Voltage Minimum Hysteresis Voltage Maximum Input Leakage Current Addition Quiescent Supply Current +Minimum Dynamic Output Current +Minimum Dynamic Output Current Maximum Quiescent Supply Current (per Package) VOUT =0.1 V TA = Worst Case VOUT = VCC - 0.1 V TA = Worst Case VOUT =0.1 V or VCC - 0.1 V TA = Worst Case VOUT =0.1 V or VCC - 0.1 V TA = Worst Case VIN=VCC or GND VIN=VCC -2.1 V VOLD=1.65 V Max VOHD=3.85 V Min VIN=VCC or GND VT - min V VH max VH min IIN ICC IOLD IOHD ICC V V A mA mA mA A * All outputs loaded; thresholds on input associated with output under test. +Maximum test duration 2.0 ms, one output loaded at a time.
