Notes:
7. Minimum voltage equals –2.0V for pulse durations of less than 20 ns.
8. Input waveform should have a slew rate of > 1 V/ns.
9. These characteristics pertain to the TAP inputs (TMS, TCK, TDI and TDO). Parallel load levels are specified in the Electrical Characteristics Table.
10. tCS and tCH refer to the set-up and hold time requirements of latching data from the boundary scan register.
11. Test conditions are specified using the load in TAP AC test conditions. tR/tF = 1 ns.
