MITSUMI I2C BUS Controlled 5-Input 2-Output AV Switch MM1492AF I2C BUS Controlled 5-Input 2-Output AV Switch Monolithic IC MM1492AF Outline This IC is a 5-input 2-output AV switch controlled by the I2C BUS developed for use in television. Because there are 2 outputs, it supports 2 screens and P-IN-P, and also supports an external output (monitor) pin. Features (1) Serial control by I2C BUS (2) 5 inputs, 2 outputs (3) 1 Y/C (S pin) inputs, 2 outputs (4) The video and audio switches can be controlled independently (5) Built-in 6dB amp for video (6) Built-in Y/C (S pin) mix circuit (7) One of the two audio outputs has a built-in -6dB ON/OFF switch (8) Slave address can be changed. 90H and 92H possible.
