This device contains circuitry protecting against damage due to high static voltage or electrical fields;
however, it is advised that normal precautions be taken to avoid application of any voltages higher than
maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused
inputs are tied to an appropriate logic voltage level (either GND or V

Absolute maximum ratings are stress ratings only; functional operation (see Table 4) at the maximums is not
guaranteed. Stress beyond those listed may affect device reliability or cause permanent damage.
Caution: VDD/VCCSYN must not exceed VDDH by more than 0.4 V at any time, including during power-on reset.
Caution: VDDH can exceed VDD/VCCSYN by 3.3 V during power on reset by no more than 100 mSec. VDDH should
not exceed VDD/VCCSYN by more than 2.5 V during normal operation.
Caution: VIN must not exceed VDDH by more than 2.5 V at any time, including during power-on reset.
Caution: These are the recommended and tested operating conditions. Proper operation outside of these conditions
is not guaranteed.
Note that for extended temperature parts the range is (-40)

VDDH, VCCSYN, and VDD must track each other and must vary in the
same direction—either in the positive direction (+0.165 VDDH and
+0.075 VDD) or in the negative direction (–0.165 VDDH and
–0.075 VDD).
