• Input Driving Sink Current :
- Minimal : 1 mA
- Normal : 5 mA
• 8x Digital Output (Open Drain)
- DO Signal have to pull up
resistor
to XCOM+ for external device, the
resistance will affect the pull up current
- Signal High Level : Pull up resistor to XCOM+
- Signal Low Level : = XCOM-
- Sink Current: 1A (Max)
