The general purpose output signals OUTPUT 1 and OUTPUT 2 are CMOS open drain outputs with
1 mA drive.

The general purpose input signals INPUT 1 and INPUT 2 are CMOS bi-directional, tri-state output
with 2mA drive.

This section describes the IO functionality, and recommended implementation.

Note 1:  The application IO can be one of the following listed types:

•

 

I

Logic input (no pull up or pull down resistors required).

•

 

IOC

Logic open-collector input.

•

 

O

Logic output (no pull up or pull down resistors required).

•

 

OOC Logic open-collector output.

•

 

I/O

Logic I/O.
