TOSHIBA TA1218F

TA1218N/F
TOSHIBA Bipolar Linear Integrated Circuit
Silicon Monolithic
TA1218N, TA1218F
Audio/Video Switching IC for TVs
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.
