The main function of the IC is to switch 7 input video sources to 5 outputs.
Each output can be switched to only one input.
It is possible to have the same input connected to several outputs.
3 of the inputs can be used as non-clamping-input, switching is controlled by bus.
The clamping function of the other 4 inputs can be overriden by external resistor divider.
The other 4 inputs can be switched to non-clamping mode with external R/C network.
All switching possibilities are controlled by the
I
2
C Bus.
All outputs can be switched to low impedance off condition by the
I
2
C Bus.
Driving 75
load requires external transistors for best performance.
The recommended coupling capacitor at each input is 47 nF.
Each clamping input requires a 75
(max. 500
) termination resistor.
Operation without or with a termination resistor greater than 500
causes malfunction
of the new high performance clamping circuit.
Unused inputs should be directly grounded.

8 bits are necessary to determine one complete configuration change.
(1 addressbyte, 5 databytes)
Minimum configuration change for 1 output needs 2
×
8 bit (1 addressbyte, 1 databyte).
Power on reset state: all 5 outputs switched to input 1, all inputs clamped, Y+C off.
