SCPS267B March 2017 – February 2020 TCA9803
The TCA980x family supports buffering use cases which do not need level-shifting or voltage-translation.
It is critical to note that there are no external sources of current allowed on the B-side ports, since this can affect device operation as shown in the IEXT-I section.
Decoupling capacitors are not shown to keep the illustration simple. Decoupling capacitors (1 µF and 0.1 µF) must be placed close to each power supply pin.
