NJM2508
3-INPUT / 2-INPUT VIDEO SWITCH
■
GENERAL DESCRIPTION
The
NJM2508
is video switch for video and audio signal. It
contanins 3 input-1 output and 2 input-1 output video switch. One
input terminal has clamp function and so is applied to fixed DC level
of video signal. Its operating voltage is 4.75 to 13V and bandwidth
is 10MHz. Crosstalk is 75dB (at f = 4.43MHz)
