SED1722/24

CMOS LCD DRIVER

CMOS 80-Bit Segment Driver

•

■ DESCRIPTION

The SED1722/24 is an 80 dot matrix LCD segment (column) driver for driving high-capacity LCD panels at

duty cycles higher than 1/100 (up to 1/500). The LSI features a wide range of LCD drive voltages.

The device uses a high-speed daisy-chain enable system which decreases power consumption and

eliminates the need for separate enable signals for each driver.

The SED1722/24 is used in conjunction with the SED1733F (100-bit output common driver) to drive a large-

capacity dot matrix LCD panel.
