Notes:
1. Applies to all control-clock inputs.
2. The Integration time is specified at room temperature such that the maximum dark current charge build up in each pixel is less than 10 percent of the minimum
saturation charge. Accordingly, it may be as long as nine seconds at room temperature. Longer integration times may be achieved by cooling the device. An
appropriate clock frequency must be chosen so that the shift register completes its operation within the desired integration time.
