IOB Output Switching Characteristics
Output delays terminating at a pad are specified for LVCMOS25 with 12 mA drive and fast slew rate. For other standards,
adjust the delays with the values shown in
Table 34: IOB Output Switching Characteristics

Product Specification
Notes:
1. A Zero “0” Hold Time listing indicates no hold time or a negative hold time. Negative values can not be guaranteed “best-case”, but
2. The 3-state turn-off delays should not be adjusted.
