SL74HC245

SL74HC245 Octal 3-State Noninverting Bus Transceiver High-Performance Silicon-Gate CMOS The SL74HC245 is identical in pinout to the LS/ALS245. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. The SL74HC245 is a 3-state noninverting transceiver that is used for 2-way asynchronous communication between data buses. The device has an active-low Output Enable pin, which is used to place the I/O ports into high-impedance states. The Direction control determines whether data flows from A to B or from B to A. 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 SL74HC245N Plastic SL74HC245D SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE PIN 20=VCC PIN 10 = GND Control Inputs 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) L H H X X = don’t care SLS System Logic Semiconductor SL74HC245 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+ St...
