AV Switch for I2C BUS Control, 4-input, 3-output
and Canal Plus Compatible
Monolithic IC MM1422, 1423, 1442, 1443
Outline
These ICs are four-input, three-output AV switches under I2C BUS control with Canal Plus support, intended
for use in VCRs and DVD for the European market. There are four models, described below. Audio
subsystems are either stereo or monaural; video subsystems either do or do not have a clamping circuit.
Features
1. I2C BUS serial control.
2. Internal two-output 75Ωvideo driver, internal two-output 600Ω audio driver.
3. Audio mute function through an external pin.
4. Operating power supply voltage 11 to 13 V
5. Models both with and without video subsystem clamp.
6. Models with monaural and stereo audio subsystems.
