DESCRIPTION ORDER CODE : TEA6417
The main function of the TEA6417 is to switch 8
video input sources on the 6 outputs.
Each output can be switched to only one of the
inputs whereas but any same input may be con-
nected to several outputs.
All the switching possibilities are controlled through
the I2C Bus.
