68-DOT COMMON DRIVER

Oki Electric Industry 

¡ Semiconductor

MSM5298A

• V1, V2, V5, VEE

Bias supply voltage pins to drive the LCD. The V1 pin can be separated from the VDD pin.

• O1 - O68

Display data output pins which correspond to each bit of the 68-bit bidirectional shift register.

One of the four levels, V1, V2, V5 and VEE, is selected based on the combination of the latched

data level and DF signal. (Refer to Truth Table.)

Connect these outputs to the common side of the LCD panel.

NOTES ON USE (when turning the power ON or OFF)

The LCD drivers of this IC require a high voltage. For this reason, if a high voltage is applied to

the LCD drivers with the logic power supply floating, excess current flows. This may damage

the IC.

Be sure to follow the sequence below when turning the power ON or OFF.

Power ON : Logic circuits ON Æ LCD drivers ON, or both ON at a time

Power OFF : LCD drivers OFF Æ logic circuits OFF, or both OFF at a time
