TA1219AN

The TA1219AN 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.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).

Features of the TA1219AN are:(1)I2C bus control;(2)video :5-channel inputs and 1-channel outputs (2 channels conforming to S system);(3)audio: 5-channel inputs and 2-channel outputs;(4)self-diagnostic function;(5)ADC inputs based on european 21-pin standards;(6)ADC inputs based on S1/S2 terminal standards;(7)switchable subaddress.

The maximum ratings of the TA1219AN can be summarized as:(1):the characteristic is supply voltage,the symbol is VCC,the rating is 14,the unit is V;(2):the characteristic is power dissipation,the symbol is PDmax,the rating is 1662,the unit is mW;(3):the characteristic is operating temperature range,the symbol is Topr,the rating is -20 to 65,the unit is ;(4):the characteristic is storage temperature range,the symbol is Tstg,the rating is -55 to 150,the unit is .When using the device at temperatures above Ta=25,reduce the rated power dissipation by 13.3mW per degree of centigrade.
