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.
