LCD segment driver
BU9706KS
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.

Featuresshift register and 40-bit latch enable serial
1) 40-bit
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 = V
