General Description
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.
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

Functional Description
NT3883 is a dot matrix LCD segment driver LSI. It
operates with the controller, such as NT3881B/C/D,
and/or another segment driver LSI NT3882A/3883.
NT3883 receives serial data from the controller or
another NT3883, converts it to parallel data and then
supplies the LCD driving waveforms to the LCD panel.

connected to GND, the data from LCD controller is fed

connected to VDD, the DL2 becomes the output of the

This signal is used for latching the shift register contents.
When CL1 is set at high, the shift register contents are
transferred to the 80-bit 4level LCD driver. When CL1 is
set at low, the last display output data (S1 to S80) is
held.

NT3882A/3883, the cascade structure is obtained to
drive a wider LCD panel. If SL2 is connected to VDD, the
st
th
DR2 becomes the input of the 41 - 80 register, in this
case, the data may come from the next NT3882A/3883.
2. CL2
Clock pulse inputs for the two 40-bit shift registers. The
data is shifted to an 80-bit latch at the falling edge of
CL2. The clock signal CL2 must be active when
operating to refresh shift registers' contents.
