Toshiba TA1218N Manual

Audio/Video Switching IC for TVs

The TA1218N/F is an audio/video switching IC for TV sets.

2

Conforming to I

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 TA1219AN

(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.
