KK74ACT623

TECHNICAL DATA www.DataSheet4U.com 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 Bus A Data Transmitted from Bus A to Bus B Buses Isolated (High Impedance State) H H H L L H 1 www.DataSheet4U.com 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 ...
