Notes:
1. These maximum values are provided for informational reasons only. Minimum output buffer resistance
values depend on VCCI, drive strength selection, temperature, and process. For board design
considerations and detailed output buffer resistances, use the corresponding IBIS models located on the
Microsemi SoC Products Group website at www.microsemi.com/soc/techdocs/models/ibis.html.
2. R(PULL-DOWN-MAX) = (VOLspec) / IOLspec
3. R(PULL-UP-MAX) = (VCCImax – VOHspec) / IOHspec
4. Output drive strength is below JEDEC specification.
