in isis i can't found LM1893 to see the result

Have you tried, like, reading the datasheet? It has complete descritption of the chip AND application diagrams.

i have a problem if i link the LM1893 directly with Pic it will caused no problem ?? because LM1893 work with 15V and the pic with 5V
also the the circuit to aliment this devices i can have 5v from 15v or i need to made anotherr circuit to have 5v ??

In Figure 4 you can see how to connect it to a 5V system.

figure4 in the datasheet??

I hoped that when you put LM1893 into google we all arrive at the same datasheet as the first link. So look here https://www.electro-tech-online.com/custompdfs/2013/04/lm2893.pdf pdf page 8, figure 4 is the only thing on that page.

the pin 5 of the LM1893 where i link it in the pic ??
