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
