Truth Table

X : Don't care

•O1 - O80

Display data output pins, which correspond to the respective latch contents. One of V1, V3,

V4 and VEE is selected as a display driving voltage source according to the combination of the

latched data level and DF signal. Refer to the Truth Table.

The outputs O1 to O80 are connected to the segment side of the LCD panel.

• DISP OFF

Input pin to control outputs of O1 to O80. V1 level is output from O1 to O80 pins during "L"

level input. Refer to the Truth Table.

Latched data

DISP OFF

LCD driver output (O1 - O80)

VEE

NOTES ON USE

Note the following when turning power on and 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 carry out the following power-on and power-off sequences:

When turning power on:

First VDD ON, next VEE, V4, V3, V1 ON. Or both ON at the same time.

When turning power off:

First VEE, V4, V3, V1 OFF, next VDD OFF. Or both OFF at the same time.
