Hi,
I am planning to use TCA9535 in my new design. It is written that there are no internal Pull Ups for the I/Os.
I am driving displays and reading some signals. Does it means that I need to put an external pullup to each and every I/O?
Also for the A1 and A0 address lines,do I have to pullup those two? In case I need them to be high.
Thanks,
Chaitanya
