What is your favorite 4000 series CMOS chip ?
-
@DamonHD interesting choice and not one I've ever used.
@Extelec IIRC ~50Y ago I was able with a #4007 to build an audio oscillator that drove a crystal earpiece, drew ~7nA (??? that's my memory!), and ran off a 470uF cap for ages!

@Extelec 4060 although I was once shocked to find that Fairchild and Phillips made chips with different output dividers with the same part number!
-
@Extelec oooh 4017 is a beauty. CD40106 hex schmidt was in many ways my 555. Loved a 4011 and a 4040. Cheekily gonna add the motorola mc series 14557B as well!
@concretedog what did you use the 14577 for ?

@Extelec as a fan of 9V batteries I'd say all of them, but 4046 especially

@Extelec
Not really my favorite but the one I know the best. For a class I implemented the 4511 on an FPGA. -

@Extelec I've just remembered a discussion about 4000 series chips where one of the designers entered the chat (actually a redesigner). I think it was the 74HC4046A, which *is* awesome but maybe HC doesn't count here.

@synx508 the 4046 (non hc) counts though, used that a lot when teslacoiling.

@Extelec why a musical tap looper design of course! https://concretedog.blogspot.com/2011/04/new-tap-looper-design.html?m=1

@concretedog ahem thats a 14557 not 14577 video amp

@concretedog ahem thats a 14557 not 14577 video amp
@Extelec doh!
-
@Extelec I got the 14557B bit right though... its a long time ago!

@concretedog It did prompt the question, I really thought there was an alternate use for the video amp chip i was unaware of

@concretedog @Extelec 40106 was also the favourite of Ray Wilson of MFOS and I can see how it could be your 555.

@synx508 @concretedog 4011 was my 555

@synx508 @concretedog and this was my bible

@synx508 @concretedog 4011 was my 555
@Extelec @concretedog Weirdly mine was 4047, because my introduction to 4000 series parts was through Tom Duncan's Adventures with Microelectronics, the followup to Adventures with Electronics. I never had the third book, Adventures with Digital Electronics, so I don't know what happened next…
-
Mine was always 4011... closely followed by 4001, 4020 and 4017.
@Extelec I once owned about 10,000 4020s that I'd bought from Bonex for £50, which also meant that I'd cycled the 11 miles home with them on a bike without panniers. It took me years to get rid of them at rallies and still find tubes of them in unexpected places. I still remember the huge box that they were originally in had a hole in it and it would occasionally launch some tubes of 4020s as I cycled home.

@Extelec thinking about it, it must've been more like 2,000, an unmanageable quantity …anyway

@Extelec Duh! 4017 - how else are you going to make LED scrollers?
