Outline
This IC is a 5-input 2-output AV switch with I2C control, developed for use in televisions. Two outputs enable it to support two screens or "picture-in-picture".

Features
1. Serial control by I2C bus.
2. 5-inputs, 2-outputs.
3. Video and audio system switches can be controlled independently.
4. 6dB 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 I2C BUS line (SDA, SCL) power supply is off.
9. Built-in 3 value discrimination function.
10.On-chip power ON reset function.
11.Two types of audio input impedance : 60kΩ and 30kΩ.
    MM1313AD : 60kΩ MM1313BD : 30kΩ
12.Supports 2-screen or P-IN-P TV.

Applications
1. Televisions
2. Other video equipment
