Philips Semiconductors Product specification
Switch for CTV receivers TDA8440
D0/OFF gating
Power-on reset
The circuit is provided with a power-on reset function.
When the power supply is switched on an internal pulse will be generated that will reset the internal memory S0, in the
initial state all the switches will be in the off position and the OFF input is active (D7 - D0= 0) (I2C mode), position defined
via SDA and SCL inputs (non-I2C mode).
When the power supply decreases below 5 V a pulse will be generated and the internal memory will be reset. The
behaviour of the switches will be the same as described above.
