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.
•Applications
Video cassette recorders and televisions
•Features
1) Three 2-input / 1-output switches (two with sync-tip
clamped inputs, the other one non-clamped).
2) 5V power supply.
3) Low power consumption (62.5mW Typ.).
•Block diagram
4) Excellent frequency characteristics
(10MHz, 0dB Typ.).
5) Wide dynamic range (clamped input: 2.9VP-P Typ.,
non-clamped input: 3.0VP-P Typ.).
6) Fast switching speed (50ns Typ.).
