The CIC481 series musical IC is the kind of IC which contains many songs of piano, organ, mandolin these three musical effects. The CIC481 has internal 8 songs. The CIC482 has internal 12 songs. The CIC483 has internal 10 songs. The songs can be single-cycle played or continuously played. The CIC481 series products use 16-pin dual package. Its pin's function is listed in the table 1 and its control function truth table is listed in table 2. The picture shows the CIC2850 series musical IC application circuit. The table 1 shows the CIC481 series musical IC's pin's function. The table 2 shows the CIC481 series musical IC's control function truth table. The last picture shows the typical circuit according to the table to control the songs output. This circuit uses the push-pull transistor output to increase the output power. C1 and C2 are used to eliminate high-frequency oscillation. It is connected a function-selection switch circuit to the pins of CE, LP, SL, /AS. Through them it could achieve every control function listed in the truth table.
