NRND - This part is not recommended for new design.

Non-RoHS - This part is not RoHS compliant.

With the acquisition of National Semiconductor Mouser
anticipates that the RoHS non-compliant National Products from
Texas Instruments will be phased out, and customers should
transition to the compliant version of the parts. The RoHS
compliant versions are available from Mouser. 

To Order - NoPb products can be ordered appending a "/NOPB"
suffix to the ordering number, for example "LM324AM/NOPB".

If you have questions about this transition to RoHS compliant
part numbers please contact a Mouser Technical Support
