The KS0794 is a 160-output segment / common driver LSI suitable for driving large scale dot matrix LC panels using as personal computers / work stations. Through the use of SST (Super Slim TCP) technology, it is ideal for substantially decreasing the size of the frame section of the LC module.
The KS0794 is good both segment driver and common driver, and a low power consuming, high-precision LC panel display can be assembled.
In case of segment mode, the data input is selected 4bit parallel input mode and 8bit parallel input mode by a mode (MD) pin.
In case of common mode, data input/output pins are bi-directional, four data shift directions are pin-selectable.

FEATURES

                                      8MHz (Max.) (Vdd = +2.4V to +4.5V)
- 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 select, causes the internal clock to be stopped
   by automatically counting 160 of input data
