2.2 Buffer Types
TABLE 2-9: BUFFER TYPES
BUFFER TYPE DESCRIPTION
IS Schmitt-triggered input
O12 Output with 12mA sink and 12mA source
VIS Variable voltage Schmitt-triggered input
VO8 Variable voltage output with 8mA sink and 8mA source
VOD8 Variable voltage open-drain output with 8mA sink
PU 50uA (typical) internal pull-up. Unless otherwise no
ted 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.
