SED1770/71

CMOS LCD DRIVER

■ DESCRIPTION

The SED1770 and the SED1771 are 160-bit output LCD segment (column) analog drivers for driving high-

capacity active matrix LCD MIM- or TFT-type panels. These devices take 3-bit analog input (VA, VB, VC)

which are (R, G, B) signals, and can support duty cycle higher than 1/100 (up to 1/500). Also, the LSI features

a wide range of LCD voltages from 5 to 17V.

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.
