BA7631中文资料罗姆数据手册PDF规格书

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.

特性 Features

1) All the audio-switching functions required for SECAM CANAL -plus decoder integrated onto one chip.

2) Inputs terminated with 65kΩ resistors.

3) Built-in output buffer.

4) Wide supply voltage range (4.5V to 13.0V).

5) Low total harmonic distortion (0.005 Typ.).

6) Wide dynamic range (3.6Vrms, VCC = 12V).

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

Applications

Video cassette recorders
