CF1155, Melody LSIs

Name OSH, LH O U T, O U T VDD VSS T1, T2, T C TO Function Melody mode control inputs.

Built-in pull-down resistors mean LOW -level signals are obtained when inputs are open circuit.

The resistance of the pull-down resistor varies with the applied voltage, as described in the Electrical Characteristi
