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,
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 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 t

and t
H, DAT
deviate from the I
2
C bus specification. After reset has been activated, transmission may
only be started after a 50 µs delay.
11. I

C bus load conditions are as follows:
4kΩ pull-up resistor to + 5 V; 200 pF to GND.
