Pin No.

I Function Output pin for the liquid crystal driver.

VDD, V2, V3 or V5 is output depending on the latch content and the DF signal.

Refer to the truth table for the output level.

1) 40-bit shift register and 40-bit latch enable serial input - parallel output. 2) Shift register can be divided into two 20-bit sections. 3) Power supply voltage: 3.5 to 6V. 4) LCD drive voltage: 3 to 6V. 5) Can accommodates duty of 1 / 8 to 1 / 16. 6) Can be used as a driver IC for static drive by setting the liquid crystal drive voltage externally (V3 = VDD, V2 = V5 = VSS, connect DF as LCD common).
