General Description
RTS26151B is a LCD driver system that is integrated with a 96-bit shift-register, a 96-bit latch-register,
level control logic and an output driver with built-in voltage booster in a single chip. Designed with
CMOS technology to provide a low-current consumption solution, RTS26151B can also be cascaded
with multiple chips to become a high resolution LCD display system.

Absolute Maximum Ratings
Comments*
Supply Voltage for Logic Circuit……...+2.4V to + 5.0V
Supply Voltage for LCD Circuit
..…..….12V to +25V (V0-VBO5)
Operating temperature....…......…………-10°C to 60°C
Storage Temperature.....…..……………-50°C to 125°C
Never allow a stress to exceed the values listed under
"Absolute Maximum Ratings", otherwise the device
would suffer from a permanent damage. Nor is a stress at
the listed value be allowed to persist over a period, since
an extended exposure to the absolute maximum rating
condition may also affect the reliability of the device, if
not causing a damage thereof.
