TDA8440

INTEGRATED CIRCUITS DATA SHEET TDA8440 Switch for CTV receivers Product specification File under Integrated Circuits, IC02 November 1985 Philips Semiconductors 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 QUICK REFERENCE DATA Supply voltage range Supply current (without load) Storage temperature Operating ambient temperature range PACKAGE OUTLINE 18-lead DIL; plastic (SOT102); SOT102-1; 1996 November 19.
