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 charactertype liquid crystal display can be easily obtained according to the number and structure of characters.
