6 OUTPUTS
POSSIBILITY OF MAC OR CHROMA SIGNAL
FOR EACH INPUT BY SWITCHING-OFF THE
CLAMP WITH AN EXTERNAL RESISTOR
BRIDGE
II BUS CONTROLLED
II 6.5dB GAIN BETWEEN ANY INPUT AND

DESCRIPTION
The main function of the TEA6414A is to switch 8
video input sources on the 6 outputs.
Each output can be switched to only one of the
inputs whereas any same input may be connected
to several outputs.
All the switching possibilities are changed through
the 3-Wire Bus (THOMSON BUS).
