LINEAR INTEGRATED CIRCUIT
3-INPUT VIDEO SWITCH WITH
75Ω 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 75Ω load and is able to connect to
TV monitor.
Its operating supply voltage range is 5 ~ 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.
