Product specification
Switch for CTV receivers
TDA8440
GENERAL DESCRIPTION
The TDA8440 is a versatile video/audio switch, intended to
be used in CTV receivers equipped with an AUXILIARY
VIDEO/AUDIO plug.
It provides two 3-state switches for audio channels and
one 3-state switch for the video channel and a video
amplifier with selectable gain (times 1 or times 2).
The integrated circuit can be used in conjunction with a
microcontroller from the MAB8400 family, and is controlled
via a bidirectional I2C bus. Sufficient sub-addressing is
provided for the I2C bus mode. It can also be controlled
directly by d.c. switching signals.
Features
• Combined analogue and digital circuitry gives maximum
flexibility in channel switching
• 3-state switches for all channels
• Selectable gain for the video channels
• Sub-addressing facility
• I2C bus or non-I2C bus mode (controlled by d.c.
voltages)
• Slave receiver in the I2C bus mode
• External OFF command
• System expansion possible up to 7 devices (14 sources)
• Static short-circuit proof outputs
