Hi all
There is a question in SNB6006PW, not a TCA9535 question.
SNB6006PW is a Japanese amusement-only IC.
Since it is close to TCA9535 IC, I will ask a question.
Is require pull-ups and pull-downs on unused I/O pins on SNB60006PW?
In TCA9535, the following description was in the datasheet.
TCA9535 Datasheet p.3
" (1) If port is unused, it must be tied to either VCC or GND through a resistor of moderate value (about 10 kΩ) "
Best Regards,
