Hi,
Kindly suggest me what should i do with the unused output ports of PCA9548A.
Thanks.
Hi,
Even the unused channels need to be terminated with their pull-up resistors, unused channels should have the same size pull-up resistors as used for the other channels, and you also need to make sure that the unused channels are disabled, please take a look at Table 4 on page 7 of the datasheet for more details about how to do this.

Have a great day,
Jose
