2 / 12 page November 1985 2 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 PACKAGE OUTLINE 18-lead DIL; plastic (SOT102); SOT102-1; 1996 November 19. Supply voltage range V15-4 10 to 13,2 V Supply current (without load) I15 typ. 33 mA max. 50 mA Storage temperature Tstg max. + 125 °C Operating ambient temperature range Tamb 0 to + 70 °C |
