TDA8540 Datasheet (NXP) - 4 X 4 video switch matrix

TDA8540, 4 X 4 video switch matrix

TDA8540 The TDA8540 has been designed for switching between composite video signals, therefore the minimum of four input lines are provided as requested for switching between two S-VHS sources.

Each of the four outputs can be set to a high impedance state, to enable parallel connection of several

* S-VHS or CVBS processing

* 3-state switches for all channels

* Selectable gain for the video channels

* sub-address facility

* Slave receiver in the I2C mode

* Auxiliary logic outputs
