TA8851CN

The TA8851CN is an A/V SWITCH IC, which has 7 input channels and 2 output channels. Because the 2 output channels can be switched independently of each other, the TA8851CN allows you to configure a PIP system input switching circuit easily. The TA8851CN can be interfaced easily to a microcontroller via the l2C bus. 3 of 7 input channels can be used for Y/C separated input.

The features of TA8851CN can be summarized as (1)video stage: input, composite video input : 7 channels, Y/C input : 3 channels; output, composite video output : 2 channels (main and sub), Y/C output : 2 channels (main and sub) ; (2)audio stage: input, L/R input : 7 channels; output, L/R output : 3 channels (2 of 3 depend on video, and the other is selectable ; (3)from main or sub) ; (4)I2C bus interface ; (5)external mute circuit ; (6)DAC output (3 outputs) ; (7)video clamp circuit ; (8)mode output ADC input (4 inputs).

The absolute maximum ratings of TA8851CN are (1)supply voltage Vcc: 13V; (2)power dissipation PDmax: 1923 (Note: When using the device at above Ta=25°C, decrease the power dissipation by 15.4m for each increase of PC. ) mW; (3)input signal voltage ein: 5Vp-p ; (4)operating temperature Topr:- 20~65°C; (5)storage temperature Tstg: - 55~150 °C.
