Hi Team,
Several questions regarding schematic design :
1. VCCA and VCCB doesn't require which side voltage level must be higher or equal to the other side, right ?
2. If DIR needs to be PU, it must be pull to VCCA side by a resistor, right?
3. Should the unused channel and DIRx be NC directly? Or suggest PD?
4. Is there a recommended resistance value for PU/PD of DIRx? Or can it be directly connected to VCC or GND?
5. If the PU/PD resistor of DIRx must be added, can several of them share the same resistor PU or PD?
We see several reference design DIR1 & DIR2 are connected to the same resistor to ground; DIR3 & DIR4 are connected to the same resistor to VCC
BR,
Kai
