Dear customers,
About the change in the name such as "Oki Electric Industry Co. Ltd." and
"OKI" in documents to OKI Semiconductor Co., Ltd.
The semiconductor business of Oki Electric Industry Co., Ltd. was succeeded to OKI
Semiconductor Co., Ltd. on October 1, 2008.
Therefore, please accept that although
the terms and marks of "Oki Electric Industry Co., Ltd.", “Oki Electric”, and "OKI"
remain in the documents, they all have been changed to "OKI Semiconductor Co., Ltd.".
It is a change of the company name, the company trademark, and the logo, etc. , and
NOT a content change in documents.

68-DOT COMMON DRIVER
This version:
MSM5298A
Nov. 1997
Previous version: Mar. 1996
GENERAL DESCRIPTION
The MSM5298A is a dot matrix LCD common driver LSI which is fabricated using low power
CMOS metal gate technology. This LSI consists of 68-bit bidirectional shift register, 68-bit level
shifter and 68-bit 4-level driver.
This LSI has 68 output pins to be connected to the LCD. By connecting two or more MSM5298As
in series, this LSI is applicable to a wide LCD panel.
FEATURES
• Supply voltage
: 4.5 to 5.5V
• LCD driving voltage
: 8 to 28V
• Applicable LCD duty
: 1/64 to 1/256
• Applicable segment driver : MSM5299A (80 outputs), MSM5299C (80 outputs)
• Package options:
80-pin plastic QFP
(QFP80-P-1420-0.80-K)
(Product name : MSM5298AGS-K)
80-pin plastic QFP
(QFP80-P-1420-0.80-BK) (Product name : MSM5298AGS-BK)
