Hello Mark,

They are the same.

The LM393DRE4 is an alternate part number for the LM393DR. If you order the "E4", you actually get the LM393DR.

We are eliminating some of the "old" "E3/4" device part numbers as all are "green" now.

Hello Mark,

Both are from Mexico. The "M" after the 23 designates Mexico. They were just from different manufacturing dates. We are not supposed to publicly disclose how we mark parts.

There was a company wide PCN change in the top marking. The TI logo and top bar was eliminated and changed to a dot and OCR-friendly fonts.
