MSM6778
120-DOT COMMON DRIVER (TAB)
This version: NMovS.M19697778
Previous version: Mar. 1996
GENERAL DESCRIPTION
The MSM6778 is a dot-matrix LCD common driver. Fabricated in CMOS technology, the device
contains two 60-bit bidirectional shift registers, two 60-bit level shifters, and two 60-bit 4-level
drivers.
The MSM6778 has 120 LCD outputs. The number of LCD outputs can be increased by cascading
MSM6778 devices, using cascade-connected I/O pins. The bias voltage which specifies a drive
level can optionally be supplied externally. The MSM6778 is suitable for various types of LCD
panel.
