NJM2245
3-INPUT VIDEO SWITCH WITH 6dB AMPLIFIER
GENERAL DESCRIPTION
The NJM2245 is a three input integrated video switch witch selects
one video or audio signal from three input signals.
It contains 6dB amplifier and its operating supply voltage range is 8.5
to 13V and bandwidth is 5MHz. Crosstalk is 65dB (at 4.43MHz).
