1. The min VILand max VIH values are based on the respective min and max LVIN values found in Table 3.
2. The symbol LVIN, in this case, represents the LVIN symbol referenced in Recommended operating conditions.
3. For recommended operating conditions, see Table 3.
This table shows IEEE 1588 DC electrical characteristics when operating at LVDD = 1.8
