Notes:
1. See “Switching Test Circuit” in the General Information Section of the Vantis 1999 Data Book.
2. These parameters are not 100% tested, but are evaluated at initial characterization and at any time the design is modified where this parameter may be affected.
3. If a signal is powered-down, this parameter must be added to its respective high-speed parameter.
