Note 2. Algebraic convention rather than absolute values is used to designate limit values.
Note 3. Current into a pin is designated as positive. Current out of a pin is designated as negative.
Note 4. DVOD = |VOD1,2 – VOD3,4| where
VOD1,2 = (VOHD1 – VOLD2) or (VOHD2 – VOLD1), and
VOD3,4 = (VOHD3 – VOLD4) or (VOHD4 – VOLD3).
Note 5. CVOD = |VOHD1 – VOHD2| or |VOHD3 – VOHD4|.
