Each input and output is protected from ground short-circuit. The 75Ω output is protected through a 75Ω resistor. Audio Switching Two electronically switched inputs : - 300mV rms input coming from internal audio. - 100mV rms input coming from the peri-TV plug one low impedance output 300mVRMS. Inputs and outputs are also protected against ground short-circuit. Switching Logic The logic takes into account the informations on 3 pins. - Internal or external video and sound (pin 8 peri TV plug) - Band III information - Video recorder key. External Video and Audio signals are selected in two cases. - When there is a voltage information coming from peri-TV plug. - When the video recorder key is selected (on TV front panel) and programmed on band III. This I.C. includes an internal switch (open collector transistor) which commutes the time constant of the horizontal PLL circuit in case of video recorder reception. 1014-03.EPS APPLICATION CIRCUIT 4/6 TEA1014 SAFETY INFORMATION FOR CRITICAL APPLICATIONS Voltage on pin 9 must not exceed the VCC voltage on pin 13. In case of risk of over voltage, use the protection as described in Figure 2. All connections to Peritel plug are terminated by low impedance loads (75W), except the external sound input. In case of risk of electrostatic discharge, use the protection as described in Figure 3. 1014-04.EPS Figure 1 : Typical Connection Between Peritel Plug and TEA2014 1014-05.EPS Figure 2 1014-06.EPS Figure 3 5/6 TEA1014 I b1 L a1 PACKAGE MECHANICAL DATA 14 PINS - PLASTIC DIP b B e E Z Z e3 D 8 1 7 a1 B b b1 D E e e3 F i L Z Min. 0.51 1.39 Millimeters Typ.
