BA7654F

Multimedia ICs 2-input, 1-output video signal switcher 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 1) Small clamp capacitors can be used (ceramic, 3000pF (Min.), 0.01µF (FZ) (recommended)). 2) Low supply voltage operation possible supply voltage range is 3.7V to 7.7V. 3) Superimposition used for fast switching speed with low switching noise (70ns Typ.). 4) Low power consumption (when VCC = 5V, 25mW Typ.). 5) Wide dynamic range (when VCC = 5V, 3.1VP-P Typ.). 6) Excellent frequency characteristics (10MHz, 0dB Typ.). 7) Low interchannel crosstalk (– 70dB Typ.). 8) Voltage can be applied to the control pins even when VCC is not applied.
