DESCRIPTION
Variable voltage Schmitt-triggered input
Variable voltage output with 6mA sink and 6mA source
Variable voltage output with 8mA sink and 8mA source
50uA (typical) internal pull-up. Unless otherwise noted in the pin description, internal pull-
ups are always enabled.
Note:
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.
50uA (typical) internal pull-down. Unless otherwise noted in the pin description, internal
pull-downs are always enabled.
Note:
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.

Note: The digital signals are not 5V tolerant. Refer to Section 5.1, "Absolute Maximum Ratings*," on
page 82 for additional buffer information.
Note: Sink and source capabilities are dependant on the VDDVARIO voltage. Refer to Section 5.1,
"Absolute Maximum Ratings*," on page 82 for additional information.
