MSM5299C
80-DOT LCD SEGMENT DRIVER
This version:
MSM5299C
Nov. 1997
Previous version: Mar. 1996
GENERAL DESCRIPTION
The MSM5299C is a dot matrix LCD segment driver LSI which is fabricated using CMOS low
power metal gate technology. This LSI consists of an 80-bit bidirectional shift register, 80-bit
latch, 80-bit level shifter, and 80-bit 4-level driver.
It receives the 4-bit parallel display data transferred from a microcomputer or an LCD controller
LSI such as MSM6255, then outputs the LCD driving waveform to the LCD.
This LSI is improved with respect to timing between load and clock in the switching character-
istics of MSM5299A. (t

However, note that the timing regulations for the load signal leading edge are added.
