Notes:
1. The part numbers of Industrial Temperature Range versions end the character “I”. Unless otherwise noted, all performance specifica-
tions quoted are evaluated for worst case in the temperature range marked on the device.
2. 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% tKC.
3. VIHQ (max) is voltage on VDDQ pins plus 0.3 V.
