MSM6669
80-DOT LCD SEGMENT DRIVER
GENERAL DESCRIPTION
The MSM6669 is a dot matrix LCD segment driver which is fabricated using CMOS low power
silicon gate technology.
This LSI consists of 80-bit latches I and II, 80-bit level shifter, and 80-bit 4-level driver.
It latches the 4-bit parallel display data from the LCD controller LSI or microcontroller, and then
outputs the signal for the LCD driving.
FEATURES
• Logic supply voltage : 2.7V to 5.5V
• LCD driving voltage : 14V to 28V
• Applicable LCD duty : 1/64 to 1/256
• Bias voltage can be supplied externally
• LCD output : 80
• 4-bit parallel data processing has improved the transfer speed to 1/4 that of the conventional
serial transfer, thereby achieving low power consumption
• Applicable common driver : MSM6778 (120 outputs)
• Structure:
TCP mounting with 35mm wide film (Product name: MSM6669AV-Z-05)
Sn-plated
Outer lead pitch : 220mm
User area : 7.5mm
