N74HC245AD

TECHNICAL DATA IN74HC245A Octal 3-State Noninverting Bus Transceiver High-Performance Silicon-Gate CMOS The IN74HC245A 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 IN74HC245A 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 IN74HC245AN Plastic IN74HC245ADW 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 301 IN74HC245A 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 ...
