Philips Semiconductors Product speciﬁcation

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,

4. Supply voltage ripple rejection = 20

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

of the used input = 1 kΩ,

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.

10. Timings tS, DAT and tH, DAT deviate from the I2C bus specification. After reset has been activated, transmission may

only be started after a 50 µs delay.

11. I2C bus load conditions are as follows:

4kΩpull-up resistor to + 5 V; 200 pF to GND.

All values are referred to VIH = 3 V and VIL = 1,5 V.
