MSM6778

E2B0031-27-Y2 ¡ Semiconductor MSM6778 ¡ Semiconductor 120-DOT COMMON DRIVER (TAB) This version: Nov. 1997 MSM6778 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.
