Variable voltage output with 16 mA sink and 16 mA source
50 µA (typical) internal pull-up. Unless otherwise noted in the pin description, internal pull-
ups are always enabled.
Internal pull-up resistors prevent unconnected inputs from floating. Do not rely on internal
resistors to drive signals external to the device. When connected to a load that must be
pulled high, an external resistor must be added.
50 µA (typical) internal pull-down. Unless otherwise noted in the pin description, internal
pull-downs are always enabled.
Internal pull-down resistors prevent unconnected inputs from floating. Do not rely on internal
resistors to drive signals external to the device. When connected to a load that must be
pulled low, an external resistor must be added.
