Explanations of the circuitry:

The bus driver input EN2 has to be connected to low potential to ensure that after transmission of a telegram the ASIC is able to listen to the transmitted data.

To minimize the capacity of the bus lines the user should avoid additional capacities. The typical capacity of a bus station should be 15 ... 25 pF.
