Need MSL data

Hello Umesh, 

  The devices listed are obsolete National Semi devices and as such, no MSL specific information is available.  

This AppNote describes the affects of humidity, and gives guidelines, during the reflow process:    http://www.ti.com/lit/an/spraby1a/spraby1a.pdf .

You can also refer to the Quality Guidelines Handbook: http://www.ti.com/support-quality/quality-policies-procedures/guidelines.html .

If these references do not provide the information you are requesting, please submit a request through our Customer Support Center: https://ticsc.service-now.com/csm  .

At your service,

~Leonard
