1 / 4 page SL74LS245 System Logic Semiconductor SLS Octal 3-State Noninverting Bus Transceiver These octal bus transceiver are designed for asynchronous two - way communication between data buses. The control function implementation minimized external timing requirements. The device allows data transmission from the A bus to the B bus or from the B bus to the A bus depending upon the logic level at the directional control (DIR) input. The enable input(E) can be used to disable the device so that the buses are effectively isolated. • Bidirectional Bus Transceiver in a High-Density 20-Pin Package • 3-state Outputs Dirve Bus Lines Directly • P-N-P Inputs D-C Loading on Bus Lines • Hysteresis at Bus Inputs Improve Noise Margins • Typical Propagation Delay Times; Port to Port ... 8 ns ORDERING INFORMATION SL74LS245N Plastic SL74LS245D SOIC TA = 0 ° to 70° C for all packages LOGIC DIAGRAM PIN 20=VCC PIN 10 = GND PIN ASSIGNMENT FUNCTION TABLE Control Inputs Output Enable Direction 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 |
