Notes:
1. Input Under/overshoot voltage must be –2 V < Vi < V_DDn +2 V not to exceed 4.6 V maximum, with a pulse width not to exceed 20% tTKC.
2. V_ILJ ≤ V_IN ≤ V_DDn
3. 0 V ≤ V_IN ≤ V_ILJn
4. Output Disable, V_OUT = 0 to V_DDn
5. The TDO output driver is served by the V_DDQ supply.
6. I_OHJ = –4 mA
7. I_OLJ = + 4 mA
8. I_OHJC = –100 uA
9. I_OLJC = +100 uA
