DESCRIPTION
The LR36685 is a CMOS vertical clock driver and
shutter driver IC for CCD area sensors which
provides the functions to convert the voltage and
impedance from the CMOS level.
FEATURES
Built-in seven circuits
2-level output :
2 circuits for vertical CCD clock driver
Output voltage level (TYP.) = 9 to 0 V
3-level output :
4 circuits for vertical CCD clock driver
Output voltage level (TYP.) = 9 to 0 to +15 V
2-level output :
1 circuit for shutter driver
Output voltage level (TYP.) = 9 to +17 V
Switchable between NTSC (EIA) and PAL (CCIR)
modes
Package :
24-pin SSOP (SSOP024-P-0275)
