Notes: 1. 100 Kilo-ohm pull-up to V
in
on open drain output; actual voltage will depend on
external impedance connected to pin.
2. Depends on the brightness level of the illumination LEDs.
3. Assumes inputs and outputs are tri-stated or high. If pulled low, current through pull up
resistors will need to be added.
4. The USB model does not support sleep mode.
5. Continuous scan.
6. Current limited by constant current rating of ferrite.
