TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA1218N, TA1218F Audio/Video Switching IC for TVs TA1218N/F The TA1218N/F 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 TA1218N/F can also be used for the PIP systems.
Furthermore, since the presence of a signal on its sync signal output pin can be determined by a microcomputer, it is possible to check each input/output channel (self-diagnosis).
This IC has the same pin assignments as the TA1219AN (SDIP36), a 1-channel output version of the TA1218N/F, so these ch...
