Talk:Intersil ICL8038

What else its applications are?

At least one popular implementation of the phreaker's blue box used a pair of them to generate the DTMF tones (though the more common version seems to have used the RadioShack audio-dialer with the timing crystals replaced). — Preceding unsigned comment added by 67.180.84.49 (talk) 15:53, 15 June 2014 (UTC)

Dates

When was it introduced? When was the clone mentioned in the article introduced? When was it discontinued?

On a different note, some applications information will be appreciated: surely, if it was cloned, and is wp notable, some substantial number were made. Which devices used them? Peace. קיפודנחש (aka kipod) (talk) 19:50, 28 November 2017 (UTC)

@קיפודנחש: According to IEEE Spectrum the introduction date is unknown. -- wikimpan (Talk) 06:39, 7 January 2019 (UTC)

The ICL8038 must have been introduced no later than 1974, and probably a little earlier. It's described briefly on p. 39 of the July 1974 issue of the amateur radio publication 73 Magazine, which simply calls it the 8038 (no "ICL" prefix). I've found Google Books references as early as 1972. --Colin Douglas Howell (talk) 00:34, 7 August 2020 (UTC)

0.001Hz

I replaced 1mHz with 0.001Hz because mHz can easily be confused with MHz, also 0.001Hz is the same way it is shown in the datasheet. I want to know why we can't use 0.001Hz? • Sbmeirow • Talk • 23:29, 7 January 2019 (UTC)

@Sbmeirow: How can a “milli” be confused with “mega”, which is a billion times larger? Thinking this way, “100 kHz” should be replaced by “100000 hertz” et cetera. Unless there are some style guides that suggest it, I see no reason for that change. -- wikimpan (Talk) 23:47, 7 January 2019 (UTC)

It's NOT "milli" vs "mega" confusion (because those words aren't used), it is "m" vs "M" where it easy to confuse them because of case issues. Also, 0.001Hz was used in the datasheet, so this is another reason. I've seen accidental confusion happen with engineering documents and product manuals in the past, which is why we quit using "mHz" and "mhz". 100 kHz has never been confusing, because there isn't an uppercase version that means something different. • Sbmeirow • Talk • 23:58, 7 January 2019 (UTC)

I’ve replaced it with “millihertz”, which should follow your idea. That should cause no confusion with ‘M’ and ‘m’. -- wikimpan (Talk) 00:31, 8 January 2019 (UTC)
