V0.0 1 12/25/2003
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 or 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 pin. The ST8009 also have analog
DC/DC converter to used.
