MSM6648

100-DOT COMMON DRIVER

GENERAL DESCRIPTION

The MSM6648 is a dot matrix LCD common driver. Fabricated in CMOS technology, the device
consists of two 50-bit bidirectional shift registers, two 50-bit level shifters, and two 50-bit 4-level
drivers.
The MSM6648 is equipped with 100 LCD output pins. By connecting more than two MSM6648s
in cascade, this LSI is applicable to a wide LCD panel.

FEATURES

• Logic supply voltage : 2.7 to 5.5 V

• LCD drive voltage : 18 to 28 V

• Applicable LCD duty : 1/64 to 1/240

• Suitable for bath panel sizes of 400 (200 ¥ 2) and 480 (240 ¥ 2) in common numbers by the use
of intermediate data input and 10-bit bypass function.

• Structure:
Tape Carrier Package (TCP) mounting with 35 mm wide film
