Notes:
1. The minimum drive strength for any LVCMOS 3.3 V software configuration when run in wide range is ±100 A. Drive
strength displayed in the software is supported for normal range only. For a detailed I/V curve, refer to the IBIS models.
2. Software default selection highlighted in gray.
3. For specific junction temperature and voltage supply levels, refer to Table 2-6 on page 2-6 for derating values.
