Part Number: BUF20800
I am considering using BUF20800 devices for liquid crystal circuits.I will attach the circuit diagram I created.First, as operation confirmation, it was confirmed whether communication of serial interface can operate normally.With this content, I would like to ask a question.Only VSD is applied as the power source for the serial interface.In this case, it can not communicate.Is it necessary to apply both VSD and VS power supply even when only communication by serial interface is operated?
