The BU9706KS is a 40-output LCD segment driver provided with a 40-bit shift register and a 40-bit latch. As the 40-bit shift register can be divided into two 20-bit sections, it can be used efficiently, based on the number of segments and the character configuration.
Also, by using a number of BU9706KS drivers, it is possible to configure an LCD segment driver of more than 80 bits.
As the liquid crystal drive voltage can be set externally to any value, it can be used as a driver IC for both static and dynamic drive in various types of liquid crystal display panels.

•Features
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).
