SL74HC623 Datasheet | System Logic Semiconductor

Octal 3-State Noninverting Bus Transceiver High-Performance Silicon-Gate CMOS The SL74HC623 is identical in pinout to the LS/ALS623. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALSTTL outputs. The SL74HC623 is a 3-state noninverting transceiver that is used for 2-way munication 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 SL74HC623N Plastic SL74HC623D 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) System Logic Semiconductor 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 from Case for 10 Seconds (Plastic DIP or SOIC Package) Value -0.5 to +7.0 -1.5 to VCC +1.5 -0.5 to VCC +0.5 ±20 ±35 ±75 750 500 -65 to +150 260 Unit V V V m A m A m A m W °C °C Maximum Ratings are those values beyond which damage to the device may occur.
