BU9768AKV General Description
The BU9768AK / BU9768AKV are man-machine interface ICs with key input, designed for portable multimedia terminals
and other devices. They can be used as drivers for operation mode display LCD panels on portable terminals,
household products, car stereos, and other appliances. Up to 126 cells can be displayed, and up to 30 keys can be
input.
Also, a maximum of four outputs are possible using expansion pins. (The number of outputs for each pin can be
changed using control codes.)
