TA1218ANG

TA1218ANG TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA1218ANG Audio/Video Switching IC for TVs The TA1218ANG is an audio/video switching IC for TV sets. Conforming to I2C bus standards, it allows you to perform various switching operations through the bus lines by using a microcomputer. Thanks to its 2-channel outputs, the TA1218ANG can also be used for the PIP systems. Furthermore, since the presence of a signal on its sync signal output pin can be www.DataSheet4U.com determined by a microcomputer, it is possible to check each input/output channel (self-diagnosis). This IC has the same pin assignments as the TA1219ANG (SDIP36), a 1-channel output version of the TA1218ANG, so these chips are pin compatible on pins 3 to 20 and 23 to 40. TA1218ANG SDIP42-P-600-1.78 Weight: 4.13 g (typ.) Features I2C bus control Video : 5-channel inputs and 2-channel outputs (2 channels conforming to S system) Audio : 5-channel inputs and 3-channel outputs Self-diagnostic function ADC inputs based on European 21-pin standards ADC inputs based on S1/S2 terminal standards Switchable subaddress 1 2005-11-15 TA1218ANG Block Diagram Det Select Det in VCC GND −6dB VinV1 VinV2 VinTV 10 28 7 12 16 38 Vout1 4 3 33 23 VCC GND Y/VinS1 Y/VinS2 ) 42 36 Vout2 Yout Yin www.DataSheet4U.com + S CinS1 CinS2 14 18 S Mute Sync separator Sync out 26 Pulse converter I C bus 2 30 + 34 32 Cout Cin 24 25 27 19 SCL SDA Address I/O1 (4 level) I/O2 (4 level) I/O3 O4 O5 ...
