description

These octal bus transceivers are designed for asynchronous two-way communicationbetween data buses. The control function implementation minimizes externaltiming requirements.

The devices allow data transmission from the A bus to the B bus or fromthe B bus to the A bus depending upon the logic level at the direction control(DIR) input. The enable input (G\) can be used to disable the deviceso that the buses are effectively isolated.

The SN54LS245 is characterized for operation over the full military temperaturerange of -55°C to 125°C. The SN74LS245 is characterized for operationfrom 0°C to 70°C.
