74ALS245

TECHNICAL DATA Octal 3-State Noninverting Bus Transceiver IN74ALS245 This device contains eight pairs of 3-state logic elements designed for asynchronous two-way communication between data buses. These circuits are suited for use in memory, microprocessor systems and asynchronous bi-directional data buses. The Enable input (E) can be used to isolate the buses. Non-inverting logic output Switching response specified into 500Ω/50 pF Switching specifications guaranteed over full temperature and VCC range Low level drive current: 54ALS = 12 mA, 74ALS = 24 mA LOGIC DIAGRAM ORDERING INFORMATION IN74ALS245N Plastic IN74ALS245DW SOIC TA = -10° to 70° C for all packages PIN ASSIGNMENT PIN 20=VCC PIN 10 = GND FUNCTION TABLE Control Inputs Output Direction Enable Operation L L Data Transmitted from Bus B to Bus A L H Data Transmitted from Bus A to Bus B H X Buses Isolated (High Impedance State) X = don’t care 1 IN74ALS245 MAXIMUM RATINGS* Symbol VCC VIN VOUT...
