Notes:

1. These maximum values are provided for information only. Minimum output buffer resistance values depend on

VCCxxxxIOBx, drive strength selection, temperature, and process. For board design considerations and detailed output

buffer resistances, use the corresponding IBIS models located on the SoC Products Group website at

http://www.microsemi.com/index.php?option=com_microsemi&Itemid=489&lang=en&view=salescontact.

2. These values are provided for a load of 100 pF and 400 pF. For board design considerations and detailed output buffer
