¡ Semiconductor 120-DOT COMMON DRIVER (TAB)
This version: Nov.M6778 MS 1997 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.
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) Tin-plating
