SPLC100A1
40-CHANNEL SEG/COM LCD DRIVER
GENERAL DESCRIPTION
The SPLC100A1 is a Liquid Crystal Display driver that contains two sets of 20-bit bi-directional shift registers, 20
data latch flip-flops and 20 Liquid Crystal Display drivers. It also features 40-channel outputs that can be applied
as common or segment driver. The SPLC100A1 receives serial display data from a display control LSI,
converts it into parallel data and supplies liquid crystal display waveforms to the liquid crystal.
FEATURES
Liquid Crystal Display driver with serial/parallel
conversion function.
Serial transfer facilitates board design.
Capable of interfacing to liquid crystal display
controllers: HD43160AH, HD61830, HD44780,
HD44790, SPLC780
