C 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 I
2
C 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 I

(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.
(9) Audio muting from external pin possible
(10) Maintains high impedance even when I
2
C BUS line (SDA, SCL) power supply is off.
(11) Built-in 3 value discrimination function built-in
(12) Built-in power ON reset function
(13) Supports 2 screens and P-IN-P. Also supports external output (monitor) pin.
