SPLC100A1 Datasheet, PDF (1/15 Pages) List of Unclassifed Manufacturers – 40-CHANNEL SEG/COM LCD DRIVER

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
