Notes:
1. Input Under/overshoot voltage must be –2 V < Vi < VDDn +2 V not to exceed 4.6 V maximum, with a pulse width not to exceed 20% tTKC.
2. VILJ ≤ VIN ≤ VDDn
3. 0 V
≤ VIN ≤ VILJn
4. Output Disable, VOUT = 0 to VDDn
5. The TDO output driver is served by the VDDQ supply.
6. IOHJ = –4 mA
7. IOLJ = + 4 mA
8. IOHJC = –100 uA
9. IOLJC = +100 uA
