Multimedia ICs Video signal switcher BA7609 / BA7609F The BA7609 and BA7609F are switching ICs developed for use in VCRs. Each contains three two-channel analog multiplexers. As one of the switches has sync-tip clamp inputs and the other two have non-clamped inputs these ICs are ideal for switching audio, video and chroma signals. Applications • Video cassette recorders and televisions Features • 1) Three 2-input / 1-output switches (one with syncclamped inputs, the other two non-clamped). 2).
