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 con-

tries. 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.

Video cassette recorders

1) All the audio-switching functions required for SECAM

CANNAL-plus decoder integrated onto one chip.

2) Inputs terminated with 140k

Ω 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.).

7) Same control logic as for the BA7630S can be used.
