Standard ICs 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, i
