General Description
The NT7704 is a 240-bit output segment/common driver LSI
suitable for driving large scale dot matrix LCD panels used
by PDA's, personal computers and work stations for
example. Through the use of COG technology, it is ideal for
substantially decreasing the size of the frame section of the
LCD module. The NT7704 is good as both a segment driver
and as a common driver, and a low power consuming, high-
precision LCD panel display can be assembled using the
NT7704. In the segment mode, the data input is selected as
4bit parallel input mode or as 8bit parallel input mode by a
mode (MD) pin. In the common mode, the data input/output
pins are bi-directional and the four data shift directions are
pin-selectable.
