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