Used as ground pin, connected to 0 V. Used as input pins of start pulse and also used as output pins for cascade connection. When "H" is input into start pulse input pin, data sampling is started. On completion of sampling, "H" pulse is output to output pin for cascade connection. Pin functions are selected by LBR. For selecting, refer to "Functional Operations". Used as input pin for selecting the shift register direction. For selecting, refer to "Functional Operations". Used as input pin for parallel transfer from sampling memory to hold memory. Data is transferred at the rising edge and output from LCD drive output pin. Used as shift clock input pin. Data is latched into sampling memory from data input pin at the rising edge. Used as reference voltage input pins. Hold the reference voltage fixed during the period of LCD drive output. For relation between input data and output voltage values, refer to "Output Voltage Value". For internal gamma correction, refer to "Gamma Correction Value". Observe the following relation for input voltage. VLS > VH0 VH8 VH63 VL63 VL56 VL0 > GND. Used as data input pins of R, G, and B colors. 6-bit data are input from data pins at the rising edge of CK. When PBS is "L", 2-pixel data are input from XA0 to XA5, YA0 to YA5, ZA0 to ZA5 and XB0 to XB5, YB0 to YB5, ZB0 to ZB5 at the same time. When PBS is "H", 1-pixel data is input from XA0 to XA5, YA0 to YA5 and ZA0 to ZA5, and fixed XB0 to XB5, YB0 to YB5 and ZB0 to ZB5 to "L" or "H". For relation between input data and output voltage values, refer to "Functional Operations" and "Output Voltage Value". Select the data to be entered into X, Y, and Z according to picture element arrays of the panel. Used as input pin for selecting the number of LCD drive outputs, which sets up operation mode with PBS pin. When "L" is entered, it becomes 324-output/2-port input mode at PBS MODE pin "L" or 321-output/1-port input mode at PBS pin "H". When "H" is entered, it becomes 312-output/2-port input mode at PBS pin "L" or 309-output/1-port mode at PBS pin "H". For selecting the number of LCD drive outputs, refer to "Output Characteristics". Used as 2-port/1-port exchange input pin to take in data. When "L" is entered, it becomes PBS 2-port input mode and 2-pixel data are input at the same time.

SYMBOL FUNCTIONS Used as LCD drive output pins which output the voltage corresponding to the input of data input pins. When 321-output mode, 3 outputs (XO54 to ZO54) are invalid. When 312-output XO1-XO108 YO1-YO108 ZO1-ZO108 mode, 12 outputs (XO55 to XO58, YO55 to YO58, ZO55 to ZO58) are invalid. When 309outputs mode, 15 outputs (XO54 to XO58, YO54 to YO58, ZO54 to ZO58) are invalid. Invalid output pins must be opened. Data of XO1 to XO108 correspond to XA0 to XA5 and XB0 to XB5. Data of YO1 to YO108 correspond to YA0 to YA5 and YB0 to YB5, and data of ZO0 to ZO108 correspond to ZA0 to ZA5 and ZB0 to ZB5. For relation between input data and output voltage values, refer to "Functional Operations" and "Output Voltage Value". Used as input pins for input data polarity exchange, POLA corresponds to XA0 to XA5, YA0 POLA POLB to YA5 and ZA0 to ZA5, and POLB corresponds to XB0 to XB5, YB0 to YB5 and ZB0 to ZB5. When "L" is entered, display data becomes normal mode. When "H" is entered, input data becomes polarity exchange mode. For relation between input data and output voltage values, refer to "Output Voltage Value". These pins are pulled down at the inside. Used as polarity exchange pins of LCD drive output. Data is taken at the term when LS is "H" and the output polarity of the LCD drive output pin is determined. Function of REV is the same as function of REV2. Input polarity exchange signal to REV, and REV2 is fixed to "L" or opened in general. When 321-output/309-output mode, it is possible to exchange output polarity between LCD driver next to each other by fixing REV2 to "L" or "H" according to position on panel. For exchanging, refer to "Output Characteristics". REV2 pin is pulled down at the inside.

Between reference voltage input pins VH0 and VH63, 63 resistors are connected in series. And between reference voltage input pins VL0 and VL63, 63 resistors are connected in series. No resistor is connected between reference voltage input pins VH63 and VL63. The correction curve is a broken line connected between intermediate voltage inputs (VH8, VH16, VH24, VH32, VH40, VH48, VH56, VL8, VL16, VL24, VL32, VL40, VL48 and VL56).

PRECAUTIONS
Precautions when connecting or disconnecting the power supply This IC has some power supply pins, so it may be permanently damaged by a high current which may flow if voltage is supplied to the LCD drive power supply while the logic system power supply is floating. Therefore, when connecting the power supply, observe the following sequence. VCC / logic input / VLS, VH0-VH63, VL0-VL63 When disconnecting the power supply, follow the reverse sequence. Reference voltage input The relation of the reference voltage input is shown here. VLS > VH0 VH8 VH56 VH63 0.5VLS VL63 VL56 VL8 VL0 > GND Maximum ratings When connecting or disconnecting the power supply, this IC must be used within the range of the absolute maximum ratings. Target output load This IC is designed for a 150 pF output load capacity. When using this IC for other than 150 pF panels, confirm the device is having no problem before using it.

NOTES :
1. Criterion of evaluating voltage deviations. (a) Between output voltage pins Measuring values : Output voltage value at the time after 10 s at the rising edge of LS. (Average of several times) (Conditions) Output load capacity is 150 pF. In a state when the reference voltage is fixed. Expecting values : Calculated following these specifications. (Conditions) In a state when the reference voltage is fixed. (b) Between LCD drivers Measuring values : Applicable to (a). (Conditions) Applicable to (a). Expecting values : Applicable to (a). (Conditions) Applicable to (a). Each input voltage between the LCD drivers must be made perfectly equal by connecting corresponding reference voltage input pins. 2. IO1 : Applied voltage = 8.0 V for output pins XO1 to ZO108. Output voltage = 7.5 V for output pins XO1 to ZO108. VLS = 10.0 V IO2 : Applied voltage = 7.0 V for output pins XO1 to ZO108. Output voltage = 7.5 V for output pins XO1 to ZO108. VLS = 10.0 V IO3 : Applied voltage = 3.0 V for output pins XO1 to ZO108. Output voltage = 2.5 V for output pins XO1 to ZO108. VLS = 10.0 V IO4 : Applied voltage = 2.0 V for output pins XO1 to ZO108. Output voltage = 2.5 V for output pins XO1 to ZO108. VLS = 10.0 V
