General Description

The NT7701 is a 160-bit output segment/common driver LSI

suitable for driving the large scale dot matrix LCD panels

used by PDA's, personal computers and work stations for

example. Through the use of SST (Super Slim TCP)

technology, it is ideal for substantially decreasing the size of

the frame section of the LCD module. The NT7701 is good

as both a segment driver and a common driver, and a low

power consuming, high-precision LCD panel display can be

assembled using the NT7701. In the segment mode, the

data input is selected 4bit parallel input mode or as 8bit

parallel input mode by a mode (MD) pin. In common mode,

the data input/output pins are bi-directional and the four data

shift directions are pin-selectable.
