| Ordering number : EN5741 CMOS LSI LC89902V CMOS Driver for VGA-Format Image Sensors Overview The LC89902V is a vertical driver CMOS IC specifically designed for use with VGA-format CCD image sensors. Package Dimensions unit: mm 3175A-SSOP24 [LC89902V] 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 V CC 3, as well as V EE 1 and V EE 2 levels (inverting). -- These drivers generate the drive levels required for the image sensor transfer gate.

The IC may be destroyed if VEE is 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 VCC and ground and between VEE and ground to eliminate noise from the power supply lines. These capacitors must have values of at least 47 F.
