LM2902K: About the difference between "LM2902-N" and "LM2902KN"

Koichiro Tazoe

Part Number: LM2902K
Other Parts Discussed in Thread: LM2902-N, LM2902, , LM2902B, LM224K, LM324K

Is ESD the only difference between "LM2902-N" (PDIP package) and "LM2902KN" (PDIP package)?

Please let me know if there are any other differences.

Also, which of the "LM2902" or "LM2902xxx" on the data sheet corresponds to the electrical characteristics of the "LM2902KN"?

The "K" suffix indicates the ESD grade.
The "-N" suffix indicates devices acquired from National Semiconductor.
(See the Design Guidelines for Devices with LM324/LM358 Cores.)

The generic part number does not include package and temperature range; the orderable part number does.

The more modern LM2902B also has better ESD protection, but is no longer available in PDIP.

Thank you for answering.

So, the electrical characteristics of LM2902KN correspond to "LM2902" in the datasheet?

Yes.

The other electrical characteristics tables mention the LM224K and LM324K, but section 6.8 forgets to mention the LM2902K. This is an error.
