TDA8440  
FUNCTIONAL DESCRIPTION  
The TDA8440 is a monolithic system of switches and can be used in CTV receivers equipped with an AUXILIARY  
VIDEO/AUDIO plug.  
The IC incorporates 3-state switches; they comprise:  
a) An electronic video switch with selectable gain (times 1 or times 2) for switching between an internal video signal  
(from the IF amplifier) and an AUXILIARY input signal.  
b) Two electronic audio switches, for two sound channels (stereo or dual language), for switching between internal  
audio sources and signals from the AUXILIARY VIDEO/AUDIO plug.  
A selection can be made between two input signals and an OFF-state. The OFF-state is necessary if more than one  
TDA8440 device is used.  
The SDA and SCL pins can be connected to the I2C bus or to d.c. switching voltages. Inputs S0 (pin 11), S1 (pin 13), and  
S2 (pin 6) are used for selection of sub-addresses or switching to the non-I2C mode. Inputs S0, S1 and S2 can be  
connected to the supply voltage (H) or to ground (L). In this way no peripheral components are required for selection.

NON-I2C BUS CONTROL  
If the TDA8440 switching device has to be operated via the AUXILIARY VIDEO/AUDIO plug, inputs S2, S1 and S0 must  
be connected to the supply line (12 V).  
The sources (internal and external) and the gain of the video amplifier can be selected via the SDA and SCL pins with  
the switching voltage from the AUXILIARY VIDEO/AUDIO plug:  
Sources I are selected if SDA = 12 V (external source)  
Sources II are selected if SDA = 0 V (TV mode)  
Video amplifier gain is 2 × if SCL = 12 V (external source)  
Video amplifier gain is 1 × if SCL = 0 V (TV mode)  
If more than one TDA8440 device is used in the non-I2C bus system, the OFF pin can be used to switch off the desired  
devices. This can be done via the 12 V switching voltage on the AUXILIARY VIDEO/AUDIO plug.  
All switches are in the OFF position if OFF = H (12 V)  
All switches are in the selected position via SDA and SCL pins if OFF = L (0 V)

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.

time of successive solder waves must not exceed  
5 seconds.  
SOLDERING  
Introduction  
There is no soldering method that is ideal for all IC  
packages. Wave soldering is often preferred when  
through-hole and surface mounted components are mixed  
on one printed-circuit board. However, wave soldering is  
not always suitable for surface mounted ICs, or for  
printed-circuits with high population densities. In these  
situations reflow soldering is often used.  
The device may be mounted up to the seating plane, but  
the temperature of the plastic body must not exceed the  
specified maximum storage temperature (Tstg max). If the  
printed-circuit board has been pre-heated, forced cooling  
may be necessary immediately after soldering to keep the  
temperature within the permissible limit.  
Repairing soldered joints  
This text gives a very brief insight to a complex technology.  
A more in-depth account of soldering ICs can be found in  
our “IC Package Databook” (order code 9398 652 90011).  
Apply a low voltage soldering iron (less than 24 V) to the  
lead(s) of the package, below the seating plane or not  
more than 2 mm above it. If the temperature of the  
soldering iron bit is less than 300 °C it may remain in  
contact for up to 10 seconds. If the bit temperature is  
between 300 and 400 °C, contact may be up to 5 seconds.  
Soldering by dipping or by wave  
The maximum permissible temperature of the solder is  
260 °C; solder at this temperature must not be in contact
