BA7632AF

Multimedia ICs Video switch for CANAL-Plus decoder BA7632AF The BA7632AF is an audio-switching ICs for decoders for scrambled pay channels used in France and other contries. 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. ᭺The BA7632AF has larger termination resistors on the inputs than the BA7631 and BA7631F. Applications Video cassette recorders Features 1) All the audio-switching functions required for SECAM CANNAL-plus decoder integrated onto one chip. 2) Inputs terminated with 140kΩ resistors. 3) Built-in output buffer. 4) Wide supply voltage range (4.5V to 13.0V). 5) Low total harmonic distortion (Max. 0.005% Typ.). 6) Wide dynamic range (3.6Vrms, VCC = 12V). 7) Same control logic as for the BA7630S can be used.
