SED1741

■ DESCRIPTION

The SED1741 is a 100 (50 × 2) dot matrix 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 daisy-chain enable system which decreases power consumption and eliminates the need for

separate enable signals for each driver.

The SED1741 is used in conjunction with the SED1742/44 (160-bit segment driver) to drive a large-capacity

dot matrix LCD panel.
