• Manufacturer: Mitsumi Electronics, Corp.

ELECTRICAL CHARACTERISTICS TEST METHOD
1. Because a description of signal input pin and pulse input pin
Sub contrast voltages V4, V9 and V14 are always set to the same
voltage, therefore only V4 is referred to in Supplementary Table.
I
Measuring conditions are as listed in Supplementary Table.
Measured with an ammeter At test point A when SW1 is set to a.
Vomax Output dynamic range
Voltage V19 is varied as described below:
1. Increase V19 gradually while inputting SG6 to pin 13 (8 or 3).

external power supply switch numbers are included in the notes
below.
Measure the voltage when the top of the waveform output at
T.P25 (30 or 35) is distorted. The voltage is called V
