Precautions for Light
Light has characteristics to move electrons in the integrated circuitry of semiconductors, therefore may change the
characteristics of semiconductor devices when irradiated with light. Consequently, the users of the packages which may
expose chips to external light such as COB, COG, TCP and COF must consider effective methods to block out light from
reaching the IC on all parts of the surface area, the top, bottom and the sides of the chip. Follow the precautions below
when using the products.
1. Consider and verify the protection of penetrating light to the IC at substrate (board or glass) or product design stage.
2. Always test and inspect products under the environment with no penetration of light.

INTRODUCTION
The S6B0086 (TQFP type: S6B2086) is a LCD driver LSI which is fabricated by low power CMOS high voltage
process technology. In segment driver mode, it can be interfaced in 1-bit serial or 4-bit parallel method by the
controller. In common driver mode, dual type mode is applicable. And in segment mode application, the power down
function reduces power consumption.
FEATURES
Power supply voltage: + 5V
