DESCRIPTION
The ST8024T is a 240-output segment/common driver IC suitable for driving large/medium scale
dot matrix LCD panels, and is used in personal computers/work stations. The ST8024T is good
both as a segment driver and a common driver, and it can create a low power consuming,
high-resolution LCD.
Number of LCD drive outputs: 240
Supply voltage for LCD drive: +15.0 to +30.0 V
Supply voltage for the logic system: +2.5 to +5.5 V
Low power consumption
Low output impedance
Shift clock frequency
Adopts a data bus system
4-bit/8-bit parallel input modes are
selectable with a mode (MD) pin
Automatic transfer function of an
enable signal
Automatic counting function which, in
the chip selection mode, causes the
internal clock to be stopped by
automatically counting 240 bits of
input data
Line latch circuits are reset when
/DISPOFF active
