GENERAL DESCRIPTION
The MSM6778B 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 MSM6778B has 120 LCD outputs. The number of LCD outputs can be increased by cascading MSM6778B devices, using cascade-connected I/O pins. The bias voltage which specifies a drive level can optionally be supplied externally. The MSM6778B 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: MSM6778BAV-Z-01) Tin-plating
