Readout Shift Register
Clocking
All gates of the 4 CCD shift registers are separated, enabling two or four output readout
modes.
To select 2 or 4 outputs operating mode, register main transport gates must be con-
nected as described here after:

not connected in order to cancel unused output amplifiers power consumption.
Operating Range
Operating range defines the temperature limits between which the functionality is guar-
anteed: 0°C to 70°C.
Absolute Maximum Ratings*
Storage Temperature ................................... -55°C to + 150°C
*NOTICE:
Stresses above those listed under absolute max-
imum ratings may cause permanent device fail-
ure. Functionality at or above these limits is not
implied. Exposure to absolute maximum ratings
for extended periods may affect reliability.
Operating Temperature .................................
0°C to + 70°C
Thermal Cycling.........................................................15°C/mm
