MITSUMI I2C BUS Control 5-Input 2-Output AV Switch MM1495X I2C BUS Control 5-Input 2-Output AV Switch Monolithic IC MM1495X Outline This IC is a 5-input, 2-output AV switch with I2C BUS control, developed for use in TV. This IC supports S2 and Cenelec standards. Features 1. Serial control by I2C BUS. 2. 5 - inputs, 2 - outputs (2 of the 5 input lines can be used for either composite or Y) 3. Built-in sync separation circuit 4. Built-in Y/C mix circuit 5. Video and audio switches can be controlled independently. 6. 6dB amp built in to video and audio systems. 7. Output voltage gain can be varied by mounting an external resistor on the audio input pin. 8. Slave address can be changed: 90H or 92H 9. Built-in 3-value identification function Package SOP-44A (MM1495XF) SDIP-42A (MM1495XD) Applications 1. TV 2.
