N-ch open-drain 4-bit I/O port (PORT4).

A pull-up resistor can be provided for

each bit (mask option). This open-

drain port has a withstand voltage of

10 V.

N-ch open-drain 4-bit I/O port (PORT5).

A pull-up resistor can be provided for

each bit (mask option). This open-drain

port has a withstand voltage of 10 V.
