Notes:

1.

Applies to all control-clock inputs.

2.

Integration time is specified at room temperature such that the maximum dark current charge build up in each pixel is

less than 10% of the minimum saturation charge. Accordingly, it may be as long as 11 seconds at room temperature

with the added capacitors. Longer integration times may be achieved by cooling the device. An appropriate clock fre-

quency must be chosen so that the shift register completes its operation within the desired integration time.
