Dot Matrix Lcd 96 Output LCD Common/Segment driver IC

Product Description

The ST8009 is a 96-output segment/common driver IC suitable for driving small/medium scale dot matrix LCD panels, and is used in PDA or electronic dictionary. The ST8009 is good as a segment driver , a common driver or a common/segment driver, and it can create low power consumption, high-resolution LCD. The ST8009 have eight modes can selected to set common and segment numbers by select register. The ST8009 also have analog DC/DC converter to used.
