BA7654F

The BA7654F is video signal switch consisting of two input pins (IN1 and IN2), one CTL pin (CTL), and one output

pin (OUT). The inputs are sync-tip clamped (synchronous edge of the video input signals are aligned to the same

voltage), and as the input impedance is extremely large, it is possible to use a small value for the clamp capacitor

(the recommended capacitor is 0.01µF (FZ) ceramic).

Applications

•

VCRs, TVs, and other equipment using video signals

Features

•

5) Wide dynamic range (when V^CC= 5V, 3.1VP-P Typ.).

1) Small clamp capacitors can be used (ceramic,

6) Excellent frequency characteristics (10MHz, 0dB

Typ.).

2) Low supply voltage operation possible supply volt-

7) Low interchannel crosstalk (– 70dB Typ.).

age range is 3.7V to 7.7V.

8) Voltage can be applied to the control pins even

3) Superimposition used for fast switching speed with

low switching noise (70ns Typ.).

4) Low power consumption

(when V^CC= 5V, 25mW Typ.).
