TDA8446

TDA8440 : 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 • Selec.

TDA8442 : The TDA8442 provides control of four analogue functions and has one high-current and two switching outputs. Control of the IC is performed via the two-line, bidirectional I2C-bus. Features • Four analogue control outputs • One high-current output port (npn open emitter) • Two switching output ports (npn collector with internal pull-up resistor) • I2C-bus slave receiver • Power-down reset.

TDA8443A : The TDA8443A is a general purpose two-channel switch for YUV or RGB signals. One channel provides matrixing from RGB to YUV, which can be bypassed. The IC is controlled via I2C-bus by seven different addresses or can be used in a non-I2C-bus mode. In the non-I2C-bus mode, control of the circuit is achieved by DC voltages.
