Description

 The TA1218F is an audio/video switching IC for TV sets.  Conforming to I² C 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 TA1218F (SDIP36), a 1-channel output version of the TA1218N/F, so 
these chips are pin compatible on pins 3 to 20 and 23 to 40.
