Note (1) current is essential constant current with supply voltage.

Note (2) determined by the longest tolerable integration time. Because of leakage current build

up, the integration time is recommended to be no greater than 10 ms.

Note (3) the maximum call out is for the modules' electrical speed. Light Source still dictates the

highest speed performance.

Note (4) this specification is a standard used by the CIS makers for the Fax Industry.

Switching Characteristics (25°C)

The Switching Characteristics (25°C) for the I/O clocks are shown in the diagram of Figure

4, on the following page. Each switch timing characteristic for each waveform is

represented by their symbolic acronym. Each corresponding switching time is defined in

the Table 7, located below Figure 4. Note: Only one video output is shown because all

four videos have identical electrical characteristic. The only physical difference is in

section 4 output, VOUT4. Section 4 has only 6 sensor chips, hence, its active scan is

shorter by 64 pixels.
