SGM9141
3-Input Video Switch
PRODUCT DESCRIPTION
FEATURES
The SGM9141 is a 3-input video switch for video signal.
It has bias input and so is applied to fixed DC level of
video signal.
Its operating supply voltage range is 4.5V to 13.2V and
bandwidth is 25MHz. Crosstalk is -73dB at 4.43MHz.
The SGM9141 is available in Green SOIC-8 and
TSSOP-8 packages. It operates over an ambient
temperature range of -40℃ to +85℃.
