KK74ACT623

TECHNICAL DATA KK74ACT623 Octal 3-State Noninverting Bus Transceiver High-Speed Silicon-Gate CMOS The KK74ACT623 is identical in pinout to the LS/ALS623, HC/HCT623. The KK74ACT623 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The KK74ACT623 is a 3-state noninverting transceiver that is used for 2-way communication between data buses. Two separate enables are available. The enable for bus A to B is active-high, the enable for bus B to A is active-low. • 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 KK74ACT623N Plastic KK74ACT623DW SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Control Inputs Output Enable PIN 20=VCC PIN 10 = GND L Direction L Operation Data Transmitted from Bus B to Bu s A Data Transmitted from Bus A to Bus B Buses Isolated (High Impedance State) H H H L L H 1 KK74ACT623 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 KK74ACT623 DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) VCC Symbol VIH VIL VOH Parameter Minimum HighLevel Input Voltage Maximum Low Level Input Voltage Minimum HighLevel Output Voltage Test Conditions VOUT= 0.1 V or VCC-0.1 V VOUT= 0.1 V or VCC-0.1 V IOUT ≤ -50 µA VIN=VIH or VIL IOH=-24 mA IOH=-24 mA VOL Maximum LowLevel Output Voltage IOUT ≤ 50 µA * * Guaranteed Limits 2 5 °C 2.0 2.0 0.8 0.8 4.4 5.4 3.86 4.86 0.1 0.1 0.36 0.36 ±0.1 -40°C to 8 5 °C 2.0 2.0 0.8 0.8 4.4 5.4 3.76 4.76 0.1 0.1 0.44 0.44 ±1.0 1.5 ±0.6 ±6.0 µA mA µA V Unit V V 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 5.5 5.5 5.5 VIN= VIH or VIL IOL=24 mA IOL=24 mA VIN=VCC or GND VIN=VCC - 2.1 V IIN ∆ICCT IOZ Maximum Input Leakage Current Additional Max.
