SMPSU use

IIRC it has also been used as an smpsu voltage convertor - but I might not RC. Tabby (talk) 03:00, 8 May 2011 (UTC)[reply]

Pinout

The pinout shown chooses colours that differ for power, capacitors, inputs and outputs.

Given that this link is found high in google's search ranks, it could be more useful : the important thing about the pins on this device are less their direction and more their voltage.

I suggest the colours are instead grouped to show TTL levels and RS232 levels to save reading the tiny label text and thinking about what Rin and Tout etc. actually imply. — Preceding unsigned comment added by 81.102.205.7 (talk) 01:08, 24 February 2018 (UTC)[reply]

Release Date vs. Creation Date

The creation date in the History section was stated to be 1987. While this is almost certainly true given the MAX232 was released in February of 1988, I cannot find a reliable source for this number. Maxim's 1988 publication talks about the release of the MAX232. I've updated the History section's wording to state that it was released in 1988 and cited a reliable source (EDN article which includes Maxim's publication from 1988). However, it's almost definitely true that the device was created in '87, so this may be worth further research through old Maxim publications or old magazines, if anyone's interested.

Although multiple sources say February 1988 for the chip, that has to be wrong since the chip came at least a couple of years earlier. Byte Magazine has a 1986 article that uses the chip in a circuit, referring to it as a "new device", even showing the chip in a circuit board. Google Books shows a lot of discussion of the chip starting in 1985. I'm kind of baffled why sources that should be authoritative say Feb 1988. KenShirriff (talk) 19:20, 11 July 2022 (UTC)[reply]

I don't doubt the 1985 date, but as you know wikipedia need references from 1985 or something that says 1985, so please post some of those links. I found a better "Electronics" July 1986 article, which is earlier than the "Byte" September 1986 article. I updated the history section and added refs to the intro section too. • Sbmeirow • Talk • 20:09, 14 July 2022 (UTC)[reply]
