Note: These are stress ratings only. Stresses exceeding the range specified under

²Absolute Maximum Ratings² may

cause substantial damage to the device. Functional operation of this device at other conditions beyond those

listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliabil-

ity.

HT0610 contains circuitry to protect the inputs against damage due to high static voltages or electric fields; however, it

is advised that normal precaution to be taken to avoid application of any voltage higher than maximum rated voltages to

logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open. This device may be light sensitive?

caution should be taken to avoid exposure of this device to any light source during normal operation. This device is not

radiation protected.
