MSM6648

E2B0029-27-Y2 ¡ Semiconductor ¡ Semiconductor MSM6648 100-DOT COMMON DRIVER This version: Nov. 1997 MSM6648 Previous version: Mar. 1996 GENERAL DESCRIPTION The MSM6648 is a dot matrix LCD common driver. Fabricated in CMOS technology, the device consists of two 50-bit bidirectional shift registers, two 50-bit level shifters, and two 50-bit 4-level drivers. The MSM6648 is equipped with 100 LCD output pins. By connecting more than two MSM6648s in cascade, this LSI is applicable to a wide LCD panel. FEATURES Logic supply voltage : 2.7 to 5.5 V LCD drive voltage : 18 to 28 V Applicable LCD duty : 1/64 to 1/240 Suitable for bath panel sizes of 400 (200 ¥ 2) and 480 (240 ¥ 2) in common numbers by the use of intermediate data input and 10-bit bypass function.
