NJM2248
3-INPUT VIDEO SUPER IMPOSER
■ GENERAL DESCRIPTION
The NJM2248 is 3-input video switch for video and audio signal.
Two input terminals have sink-chip clamp function and so it is
applied to fixed DC level of video signal. The other input terminal is
transistor base input for luminant signal and so luminant level may
be easily fixed by outer circuit. Its operating supply voltage range is
4.75 to 13V and bandwidth is 10MHz. Cross-talk is 70dB (at
4.43MHz).
