Overview
The LC89902V is a vertical driver CMOS IC specifically
designed for use with VGA-format CCD image sensors.
Applications
• Image input units and similar products
Features
•
CMOS structure supporting low power dissipation.
• Level shifter circuits provided on chip to minimize the
number of external components required.
• Miniature package (24-pin SSOP)
Functions
• Inverting drivers: 6 channels
— Converts input pulses to VCC1, VCC2, and VCC3, as
well as VEE1 and VEE2 levels (inverting).
— Generates the drive levels required for the image
sensor imaging and storage sections.
• Inverting drivers: 2 channels
— These drivers convert input pulses to VCC1, VCC2,
and VCC3, as well as VEE1 and VEE2 levels
(inverting).
— These drivers generate the drive levels required for
the image sensor transfer gate.

Usage Notes
• Power supply application timing
When applying power to the LC89902V, either both power-supply voltages must be turned on at the same time or V
CC
(+5 V) must be turned on before VEE(–10 V) is turned on. The IC may be destroyed if VEEis turned on first.
• Power supply noise elimination
Clock frequency noise may occur on the power supply lines due to the charge and discharge currents required to drive
the CCD. Capacitors must be inserted both between VCCand ground and between VEEand ground to eliminate noise
from the power supply lines. These capacitors must have values of at least 47 µF.
