I2C BUS Control 4-Input 1-Output AV Switch MM1311
I2C BUS Control 4-Input 1-Output AV Switch
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 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.
MM1311AD : 60kΩ MM1311BD : 30kΩ
Package
SDIP-32A (MM1311AD, MM1311BD)
Applications
1. Television
2. Other video equipment

Example of Application Circuit
I2C BUS Control 4-Input 1-Output AV Switch MM1311
Notes 1 : VOUT is set at 4.4V and CIN at 4.3V.
Please note that capacitance polarity may vary depending on
comb filter bias.
Notes 2 : Each audio output can be muted by making pin 19 high. Mute is
off when it is open or low.
