FUNCTIONAL DESCRIPTION  
Pin Functional Description  
• DI  
Shift register data input pin which inputs the data on scanning lines in synchronization with  
aclock(positive logic). ThisLSIcanoptionallydividethe scanningsignal up to 1/32dutyLCD  
panel because it consists of the 32-bit shift register.  
• CP  
Clock pulse input pin for the 32-bit shift register. The data is shifted to the 32-bit shift register  
at the falling edge of the clock pulse. A data set up time (t ) and data hold time (t ) are

HOLD  
required between DIandCP. (RefertoSwitchingCharacteristics.)ASchmitt circuit is included  
in the CP input circuit.  
• DF  
Synchronous signal input pin for alternate signal for LCD driving.  
• V , V  
DD SS  
V
DD  
is a power supply pin, which is normally from 3.0V to 7.0V. V is a ground pin, which

is 0V.  
• O - O
