MSM6778
120-DOT COMMON DRIVER (TAB)
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.
FEATURES
• Logic supply voltage : 2.7 V to 5.5 V
• LCD drive voltage : A wide range from 18 V to 28 V
• Applicable LCD duty : 1/100 to 1/256
• The bias voltage can be externally supplied.
• Structure:
35mm-wide Tape Automated Bonding (TAB) film (Product name: MSM6778AV-Z-01)
