I/O versions:
8 open-drain I/O ports with
latching transition detection
interrupt and selectable
pullups.
Open-drain outputs can
level shift the logic-high
state to a higher or lower
voltage than V+ using
external pullup resistors.
Any port can be used as an
input by setting the open-
drain output to logic-high.
Transition flags identify
which inputs have changed
(even momentarily) since
the ports were last read.

8 open-drain I/O ports with
nonlatching transition
detection interrupt and
pullups on all ports.
All ports power up as inputs
(or logic-high outputs).
Any port can be used as an
input by setting the open-
drain output to logic-high.
