■ GENERAL DESCRIPTION
One input terminals has sink-chip clamp function and so it is applied to
fixed DC level of video signal. Two other input terminals are 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).
