ƔDescription

The BA7654F, BA7653AF/AFV, 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 ȝF (FZ) ceramic capacitor is recommended).

ƔFeatures

1) Low value clamp capacitance can be used (Min. 3000 pF Recommended 0.01ǴF (FZ) ceramic capacitor)

2) Low voltage operation is possible (Operating range 4.0ጚ7.0V)

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)

ƔApplications

VCR, TV, and other applications that use display signals.
