SED1733

CMOS 100-Bit Common Driver

High-Voltage LCD Driver

•

■ DESCRIPTION

The SED1733 is a 100-bit output LCD common (row) 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 signals for each driver.

The SED1733 is used in conjunction with the SED1722 or SED1724 segment drivers to support a large-

capacity dot matrix LCD panel.
