SED1191

CMOS LCD 64-COMMON DRIVER

■ DESCRIPTION

The SED1191 is a dot matrix LCD common (row) driver for driving high-capacity LCD panel at duty cycles

higher than 1/64. The LSI uses two serially connected, 32-bit shift registers to hold the display data, and level

shifter converts the TTL level 64-bit parallel data from the shift registers to levels suitable for use by the LCD

drive circuitry. The SED1191 generates common drive signals using the voltages supplied to LCD drive

voltages pins.

The SED1191 is used in conjunction with the SED1181 (64-bit row driver) to drive a large-capacity dot-matrix

LCD panel.
