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
Pin Configuration
T LCD driving voltage range (VDD - VEE): 3.5V to 11V
T Applicable LCD duty cycle: 1/2 to 1/16
T Interfaces with a NT3881B/C/D LCD controller
T LCD bias voltage can be supplied externally
T Available in 100-pin QFP and in CHIP FORM
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.
