• LOAD OUT

This is the output pin for the display data load signal. The load signal that is input to the LOAD

IN pin is output from this pin via a buffer.

• SEG-TEST IN

This is the input pin for making all segments ON. When this pin is “H”, all segment outputs

(SEG1 to SEG160) become ON irrespective of the display data and the Blank signal. When this

pin is made “L”, each of the segment outputs (SEG1 to SEG160) become ON or OFF according

to the display data.

• SEG-TEST OUT

This is the output pin for making all segments ON. The segment ON signal that is input to at

the SEG-TEST IN pin is output via a buffer.

• BLANK IN

This is the input pin for making all segments OFF. When this pin is “H”, all segment outputs

(SEG1 to SEG160) become OFF irrespective of the display data. When this pin is made “L”, each

of the segment outputs (SEG1 to SEG160) becomes ON or OFF according to the display data. The

BLANK IN is valid when the segment ON signal is "L".

• BLANK OUT

This is the output pin for making all segments OFF. The segment OFF signal that is input to the

BLANK IN pin is output via a buffer.

• SEG1 to SEG160

These are the signal outputs for driving the LCD segments and are connected to the corresponding

segment pins of the LCD panel.

During the Static mode of operation:

The SEGn output corresponds to bit n of the display data in the data latch A. The display data

in the data latch B becomes invalid. In the segment ON condition, a signal with a phase opposite

to that of the COM OUT signal is output from these pins. In the segment OFF condition, a signal

with a phase identical to that of the COM OUT signal is output from these pins.

During the 1/2 duty dynamic display mode of operation:

The SEGn output corresponds to bit n of the display data in the data latch A when COM A has

been selected and to bin n of the display data in the data latch B when COM B has been selected.

In the segment display ON condition, a signal opposite in phase to that of the selected COM

output is output from these pins. In the segment display OFF condition, a signal identical in

phase to that of the selected COM output is output from these pins.

• COM A, COM B

These are the outputs for LCD display and are connected to the common pins of the LCD panel.

During the Static mode of operation:

COM A and COM B both output a signal with the same phase as that of the COM OUT signal.
