Switch for CTV receivers

TDA8440

Notes to the characteristics

1. Also if the supply is switched off.

2. Caused by drive on any other input at maximum level, measured in B = 5 MHz, source impedance

for the used input 75

Ω,

3.

4. Supply voltage ripple rejection = 20

5.

6. Caused by drive of any other input at maximum level, measured in B = 20 kHz, source impedance

of the used input = 1 k

Ω,

7. f = 20 Hz to 20 kHz.

8. All outputs are short-circuit proof (static).

9. The inputs and output (apart from SDA, SCL and OFF) withstand tests of MIL-STD-883 C. It is advisable to

connected series resistors to these pins.
