Communication ICs Panel interface BU8310AK / BU8311KS / BU8313K The BU8310AK, BU8311KS, and BU8313K are large-scale integrated circuits for telephones, which enable a serial input / output interface between the key input required for telephone panel boards and LED control functions.

They reduce the number of wiring harnesses needed between the main board in the telephone and the panel board, and take some of the processing load off the main CPU.

FApplications Telephones and cordless telephones
