General Description

The NT3882 is a dot matrix LCD 40 channel driver

fabricated by low power CMOS technology. This IC

consists of two 20-bit shift registers, a 40-bit latch, and a

40-bit 4 level LCD driver. The NT3882 converts serial

data which is received from the LCD controller

(NT3881C/D) to parallel data and then 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.
