Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'NT' corresponds to the 24-pin PDIP package variant when sourcing. Confirm RoHS compliance status through official Texas Instruments documentation, as manufacturing processes may vary by production lot. Ensure the supplier provides valid traceability for this obsolete or legacy component series.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring precise 25-ohm termination characteristics for memory interfaces. The octal architecture reduces board space compared to using multiple quadruple buffers. Verify that the required operating temperature range aligns with the industrial specification limits defined in the datasheet.
