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 model on the Actel website at http://www.actel.com/download/ibis/default.aspx.

2. R(PULL-DOWN-MAX) = (VOLspec) / IOLspec

3. R(PULL-UP-MAX) = (VCCImax – VOHspec) / IOHspec

4. Applicable to IGLOO PLUS V2 devices operating at VCCI

≥ VCC.
