Overview
Multimedia ICs 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.
).
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.
).
