Part Number: CD4043B

Hello,

I considering thermal analysis of circuit board using CD4043BD.

I would like to confirm thermal impedance data of CD4043BD.

(Thermal impedance of junction to ambient and junction to board)

* The data sheet of CD4043B does not provide thermal impedance data.

Regards,

Hey MESH,

I'll need to make a thermal request to get this information. Please allow 1-2 weeks for me to get back to you with this information.

Thanks,
Rami
