Four I/O, four output-only versions:
Four open-drain I/O ports with latching transition
detection interrupt and selectable pullups.
Four push-pull outputs with selectable power-up
default levels.
PCF8574-, PCF8574A-compatible versions:
Eight 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.
Software equivalent to a MAX7320 plus a MAX7321.
Software equivalent to a MAX7320 plus a MAX7319.
