The TA872OAN is designed as one kind of multi-channel electronic switch integrated circuit that can be used in all kinds of video and audio equipment as the multi-channel signal switch. 1.Features The TA872OAN has the multi-channel electronic switch circuit and the multi-channel 6dB amplifier to amplify the transmitted signals to 6db then sends the signals to the post-stage circuit. 2.Pin functions and data The TA872OAN can be used in large screen color TV as the TV/AV (S-VHS) electronic switch, the pin functions and data is as shown in table 4. This IC uses the 30-pin plastic dual in-line structure. The internal conversion circuit is divided into two parts, the video part and the audio part, it has the noise reduction function, and it is controlled by the signals from the single-chip microcomputer.
