3-INPUT VIDEO SWITCH WITH 75Ω DRIVER
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJM2244 is a three input integrated video switch witch selects one
video or audio signal from three input signals.
It contains driver circuit for 75Ω load and is able to connect to TV monitor.
Its operating supply voltage range is 5 to 12v and bandwidth is 10MHz.
Crosstalk is 70dB (at 4.43MHZ).
NJM2244 contains clamp function and it can be operated while setting DC
level fixed in position of the video signal.
