MSM5298A
68-DOT COMMON DRIVER
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)
