TA1218N/F2000-09-11 1/40TOSHIBA Bipolar Linear Integrated Circuit Silicon MonolithicTA1218N, TA1218FAudio/Video Switching IC for TVsThe TA1218N/F is an audio/video switching IC for TV sets.Conforming to I 2C bus standards, it allows you to performvarious switching operations through the bus lines by using amicrocomputer. Thanks to its 2-channel outputs, the TA1218N/Fcan also be used for the PIP systems. Furthermore, since thepresence of a signal on its sync signal output pin can bedetermined by a microcomputer, it is possible to check eachinput/output channel (self-diagnosis).This IC has the same pin assignments as the TA1219AN(SDIP36), a 1-channel output version of the TA1218N/F, sothese chips are pin compatible on pins 3 to 20 and 23 to 40.Features• I 2C 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• Switchable subaddressTA1218NTA1218FWeightSDIP42-P-600-1.78 : 4.13 g (typ.)QFP48-P-1014-0.80 : 0.83 g (typ.)• TOSHIBA is continually working to improve the quality and reliability of its products.
