GENERAL DESCRIPTION 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 devices.
