LC7442

The LC7442 is memory controller for PIP systems for TV sets and VCRs.Since this IC includes 3 built-in D/A converter circuits on chip,a component-type PIP system can be contructed by combining this product with memory and an A/D converter such as the LC7480.

The absolute maximum ratings of the LC74421 can be summarized as:(1):the parameter is maximum supply voltage,the symbol is VDDmax,the rating is -0.3 to +7.0,the unit is V;(2):the parameter is maximum input voltage,the symbol is IINmax,the rating is -0.3 to VDD+0.3,the unit is V;(3):the parameter is maximum output voltage,the symbol is VOUTmax,the rating is -0.3 to VDD+0.3,the unit is V;(4):the parameter is allowable power dissipation,the symbol is Pd1max(DIP version),the rating is 500,the unit is mW;(5):the parameter is allowable power dissipation,the symbol is Pd2max(OFP version),the rating is 350,the unit is mW;(6):the parameter is operating temperature,the symbol is Topr,the rating is -10 to +70,the unit is ;(7):the parameter is storage temperature,the symbol is Tstg,the rating is -55 to +125,the unit is .
