General Description
The NT3883 is a dot matrix LCD 80-channel driver
fabricated by low power CMOS technology. This IC
consists of two 40-bit bi-directional shift registers, 80-bit
latch and 80-bit 4-level LCD driver. The NT3883 converts
serial data that are received from the LCD controller, such
as NT3881B/C/D, to parallel data and outputs LCD driving
waveforms to drive LCD. Expansion of character-type
liquid crystal display can be easily obtained according to
the number and structure of characters.
