Table 1. Maximum Ratings(1)

(Voltages Referenced to VSS)

1. Maximum Ratings are those values beyond which damage to the device may occur. This device contains protection circuitry to guard against

damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than

maximum rated voltages to this high-impedance circuit. For proper operation, Vin and Vout should be constrained to the range VSS ≤ (Vin or

Vout) ≤ VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left

open.
