Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:  1.  Integration time is calculated as follows:
t
int(min)
= (256 18) y clock period + 20 ms
where 256 is the number of pixels in series, 18 is the required logic setup clocks, and 20 ms is the pixel charge transfer time (t
qt
)
2.  SI must go low before the rising edge of the next clock pulse.
