QW-R121-005,A
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.

APPLICATION
Oscillation Prevention on light loading conditions Recommended under circuit
This IC requires 1M resistance between INPUT and GND pin for clamp type input since the minute current causcs
an unstable pin voltage.
