●Description
The BA7654F, BA7653A F/FV or BA7652AF is a video signal (display signal) switch containing one 2-input or 3-input circuit.
Each of the input pin formats is “sync-tip clamp input” that matches the synchronous tips of video signals (display signals) to
the same potential. The inputs have an high input impedance configuration, in which they can utilize a small clamp capacitor
(0.01 µF (FZ) ceramic capacitor is recommended).
●Features
1) Low value clamp capacitance can be used (Min. 3000 pF Recommended 0.01µF (FZ) ceramic capacitor)
2) Low voltage operation is possible (Operating range 4.0～7.0V)
3) Superimposed can be applied since switching speed of SW is fast and there is little switching noise (Typ. 70ns)
4) Low power consumption (Typ. 25mW when Vcc=5V)
5) Large dynamic range (Typ. 3.1VP-P when Vcc=5V)
6) Good frequency characteristics (Typ. 10 MHz 0 dB)
7) Low interchannel crosstalk (Typ. –70 dB)
8) Voltage can be applied to the CTL pin without a VCC voltage.
9) Built-in mute function (BA7652AF)
●Applications
VCR, TV, and other applications that use display signals.
