Notes

1.All voltages are referenced to ground.

2.Input levels equal either Vcc or GND.

3.The output must be configured to source.

4.The output must be configured to have pull-up resistance enabled.

5.This is the time for one comparison. The cycle is multiplied by 3.

6.This parameter is measured with maximum output current.
