Monolithic IC MM1311
Outline
This IC is a 4-input 1-output AV switch with I2C control, developed for use in televisions.
Features
1. Serial control by I2C BUS.
2. 4 inputs, 1 output.
3. Video and audio system switches can be controlled independently.
4. 6 dB amplifier built in to video system.
5. Built-in Y/C MIX circuit.
6. Slave address can be changed : 90H or 92H.
7. Audio muting possible by external pin.
8. Maintains high impedance even when I
9. Built-in 3 value discrimination function.
10. On-chip power ON reset function.
11. Two types of audio input impedance : 60kΩ and 30kΩ.
