SN54LS245 - Octal Bus Transceivers With 3-State Outputs

Updated : 2020-01-09 14:36:02
Description

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.

Products containing the "SN54LS245" keyword are: SN54LS245/SN74LS245 , SN54LS245FS , SN54LS245J
Features

  • 3-State Outputs Drive Bus Lines Directly
  • PNP Inputs Reduce DC Loading on Bus Lines
