Other Parts Discussed in Thread: BUF12840, BUF16821
BUF16821-Q1 has the following two power supplies.
・ Digital power supply: VSD
・ Analog power supply: VS
Here, is it possible to output data by applying analog power (VS) after digital power (VSD) after receiving data with I2C while only digital power (VSD) is applied?
The points of the question are as follows.
-Can I2C data be received only by applying digital power (VSD)?
-After receiving I2C data, is the voltage output by applying the analog power supply (VS)?
For reference, for the consumer version BUF12840 similar to BUF16821-Q1,
As shown in the data sheet below, only the digital power supply (VSD) can be applied.
I2C data reception is guaranteed.
However, BUF16821-Q1 is not described, so we contacted you.
