SED1742/44

June 1997

CMOS 160-BIT SEGMENT DRIVER

HIGH VOLTAGE LCD DRIVER

■ DESCRIPTION

The SED1742/SED1744 is a 160 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

voltages. The upper and lower LCD drive voltages (V0, V5) are independent of the chip supplies.

This enables the LCD drive bias voltages to be supplied from an external source. The device uses

a daisy-chain enable system which decreases power consumption and eliminates the need for

separate enable signals for each driver.

The SED1742/44 is used in conjunction with the SED1743 (160-bit common driver) to drive a

large-capacity dot matrix LCD panel.
