UTC M3366
LINEAR INTEGRATED CIRCUIT
3-INPUT VIDEO SWITCH WITH 75 DRIVER
DESCRIPTION
The UTC M3366 is a three input integrated video switch selects one video or audio signal from three input signals. It contains driver circuit for 75load 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). The UTC M3366 contains clamp function and it can be operated while setting DC level fixed in position of the video signal.
