40-DOT SEGMENT DRIVER
This version: _MN_Sov_M. ₅1₈99₃7_9B
Previous version: Mar. 1996
GENERAL DESCRIPTION
The MSM5839B is a dot matrix LCD segment driver LSI which is fabricated using low power
CMOS metal gate technology. This LSI consists of two 20-bit shift registers, two 20-bit latches,
a 40-bit level shifter and a 40-bit 4-level driver.
It converts serial data, which is received from an LCD controller LSI, to parallel data and outputs
LCD driving waveform to the LCD panel.
Expansion of display can easily be made by increasing the number of characters and character
patterns.
This LSI can drive a variety of LCD panels because the bias voltage, which determines the LCD
driving voltage, can be optionally supplied from the external source.
