GENERAL DESCRIPTION
The MSM6568A is a dot matrix LCD common driver which is fabricated in CMOS technology. The MSM6568A consists of two 80-bit bidirectional shift registers, two 80-bit level shifters, and two 80-bit 4-level drivers. The MSM6568A is equipped with 160 output pins. By connecting two or more MSM6568A devices in cascade, the number of LCD outputs can be increased. www.DataSheet4U.com The MSM6568A can drive a variety of LCD panels because the bias voltage, which determines the LCD driving voltage, can be optionally supplied from an external source.
FEATURES
Logic supply voltage : 2.7 to 5.5V LCD driving voltage : 14 to 28V Applicable LCD duty : 1/64 to 1/256 External bias power supply available Package : TCP mounting with 70mm wide film (Product name : MSM6568AV-Z) Tin-plated
