IN74HC623A

TECHNICAL DATA IN74HC623A Octal 3-State Noninverting Bus Transceiver High-Performance Silicon-Gate CMOS The IN74HC623A is identical in pinout to the LS/ALS623. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. The IN74HC623A 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. 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 IN74HC623AN Plastic IN74HC623ADW SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Control Inputs PIN 20=VCC PIN 10 = GND Output Enable 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) w w w .d h s a t a ee . u t4 m o c L H H L L H 1 www.DataSheet4U.com IN74HC623A 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 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 fr...
