keyboard encoder chip

[cronxeh]

Ive disassembled a keyboard that I was going to throw away and took out this chip:

Chicony
ver-c
105-06868-031
6868A-10063
0008M
E1GG1



I'm wondering if its an IC that i can use in any other applications. If anyone knows how the keyboard encoders work or have any schematics please let me know
