- I'm not sure "notorious" is the right adjective, since it has a connotation of being bad. Some engineers might have groaned at the number of designs that used such chips in scenarios where alternatives might have been cheaper, or that would have benefitted from the DSR/DTR/DCD/RI, but the MAX-232 was a good solid "It Just Works" device for applications which could get by with Rx/Tx, and one additional pair of transmit/receive pins (usually RTS and CTS).supercat– supercat2025-01-13 16:01:14 +00:00Commented Jan 13 at 16:01

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. ms-dos), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
