Video signal switcher
BA7607 / BA7607F
The BA7607and BA7607F are switching ICs developed for use in VCRs. Each contains three two-channel analog
multiplexers. As two of the switches have sync-tip clamp inputs and the other one has non-clamped inputs these ICs
are ideal for switching audio, video and chroma signals.
