port B output staying LOW.
The port A current source has a typical value of about 1 mA, but varies with both V
port A current source current drops to 0 mA. The current source current dropping across the internal pull-down driver resistance of
about 200
As long as the chip ground is common with the input ground reference the driver resistance may be as large as 120 . However, ground
offset will rapidly decrease the maximum allowed driver resistance.
Guaranteed by design.
