Hello,
I noticed in the TCA6408A manual (ver. SCPS192E) on page 3 that it is recommended to connect the ADDR pin directly to VCCP or GND.
However, in the layout example on page 33, the ADDR pin is connected to VCCI.
If I am using a configuration where VCCP is 1.8V and VCCI is 3.3V, what would be the difference between connecting ADDR to VCCI versus VCCP?
Which would be the better choice?
Sincerely,
Dennis
