TDA8540 Description
TDA8540 The TDA8540 has been designed for switching between posite 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. 8.8 30 − − − V UNIT mA dB MHz dB ORDERING INFORMATION TYPE NUMBER TDA8540 TDA8540T PACKAGE NAME DIP20 SO20...
