NJM2283
2-INPUT 3CHANNEL VIDEO SWITCH
■
GENERAL DESCRIPTION
NJM2283
is a switching IC for switching over from one audio or
video input signal to another. Internalizing 2 inputs and I output,
and then each set of 3 can be operated independently. It is a
higher efficiency video switch, featuring the supply voltage range
4.75 to 13.0V, the frequency feature 10MHz, and then Crosstalk
75dB (at 4.43MHz).
