Notes:
1. See “Switching Test Circuits” in the General Information section of the Vantis 1999 Data Book.
2. MACH221 tGO = 7 ns. MACH221SP tGO = 8 ns.
3. 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.
4. If a signal is powered-down, this parameter must be added to its respective high-speed parameter.
