TA1218F Datasheet Audio/video Switching

Manufacturer: Toshiba

Overview: 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 chips are pin compatible on pins 3 to 20 and 23 to 40.

This datasheet includes multiple variants, all published together in a single manufacturer document.
