Multimedia ICs Video switch for CANAL-Plus decoder BA7631 / BA7631F The BA7631 and BA7631F are audio-switching ICs for decoders for scrambled pay channels used in France and other countries. The ICs include a five-input multiplexer, a four-input multiplexer and a two-input multiplexer, and allow decoder audio switching to be done with a single IC. When used in combination with the BA7630S common logic control can be used for audio and video switching. Applications Video cassette recor.
