PCA9617A

In the PCA9617A data sheet, is it necessary to have a high pulse after ACK on SDA in Figure 8.

When level conversion of data (part of slave register address) from SDAA to SDAB of PCA 9617A, the data may change  probably because there is not the high pulse.

Hi Naoyuki,

It is common to have such a high pulse after the ACK and before the next data byte because the SDA line is no longer pulled low by the slave. During that time it is pulled high through a pull-up resistor.
