These ICs are four-input, three-output AV switches under I
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.
1. I
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
5. Models both with and without video subsystem clamp.
6. Models with monaural and stereo audio subsystems.
