CMOS LCD 64-SEGMENT DRIVER
s
DESCRIPTION
The SED1180 is a dot matrix LCD segment (column) driver for driving high-capacity LCD panel at duty cycles
higher than 1/64. The LSI contains 64-bit shift register for display data. The display data is supplied through
4-bit bus, and serially transferred through 16
脳
4 bit shift register. The display data is held in a 64-bit latch
circuit. The LSI converts the level of the latched data to an LCD drive waveform.
The SED1180 is used in conjunction with the SED1190 (64-bit row driver) to drive a large-capacity dot matrix
LCD panel.
