SN54LS245-SP Datasheet PDF - TI

These octal bus transceivers are designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements.

●The SNx4LS245 devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can disable the device so that the buses are effectively isolated.

● 3-State Outputs Drive Bus Lines Directly

● PNP Inputs Reduce DC Loading on Bus Lines

● Hysteresis at Bus Inputs Improves Noise Margins

● Typical Propagation Delay Times Port to Port, 8 ns
