BA7631F

 All the audio-switching functions required for SECAM CANAL -plus decoder integrated onto one chip.
Inputs terminated with 65k resistors.
Built-in output buffer.
Wide supply voltage range (4.5V to 13.0V).
Low total harmonic distortion (0.005% Typ.).
Wide dynamic range (3.6Vrms, V_CC = 12V).
Same control logic as for the BA7630S can be used.

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.
