What logic and digital chips to get ?

Alex Eisenhut:
No point in storing jelly bean parts beyond what you need for the current project. I threw away lots of useless parts and shrank down from three to one storage cabinet.

I only keep 74LS and small DRAMs for my Commodore stuff. That's it.

Also esd foam has a finite life span. Some of the crap I had for 10 - 20 years also became useless as the foam disintegrated on the pins and corroded them.

Tells me I didn't need those parts, except as a trophy. So out they go!

You might find a small collection of shift registers and (de)multiplexers of use to expand the I/O of your microcontroller:

74HC151 - 8-line to 1-line data selector / multiplexer
74HC154 - 4 to 16-line decoder / demultiplexer
74HC164 - 8-bit serial in parallel out shift register
74HC165 - 8-bit parallel in serial out shift register
74HC594 - 8-bit serial in parallel out shift register with output registers
74HC595 - 8-bit serial in parallel out shift register with tri-state outputs

The serial in parallel out shift registers are a popular choice for multiplexing 7-digit / dot matrix displays.

You can get assorted 4000 series and 74HCxx series kits from Amazon or Ebay fairly inexpensively .They can range from a few bucks to around 30 dollars and have the most used popular chips in the kits.And come in either TTL or CMOS for both series.

I used to hoard components as well, until I started doing this thing once a year: The Giveaway!

I post photos of stocks of components (a bunch of OpAmps, power transistors, passives, transformers, you name it) on my local forum, literally giving it all away to students/makers/tinkerers in my area.
That damn BC547 makes a lot more sense sparkling fire on a breadboard instead of aging in my drawer!

People are usually extremely grateful for that, and my garage looks clean again. :-)

I have half an assortment box with 74HC/T parts; most commonly I have need for 74HC04 and 74HC74, but also for others when I resume working on my Z80 board from time to time.
I still like working with logic chip out of convenience.

Since I like prototyping randomly at any possible electronic topic - computer-, ham- or audio related, I have a proper stock of jellybean components and some more particular chips; certainly what is used most is the storage box with 0805 Cs and Rs - which I prefer over wired components.
