Just buy them in bulk from ebay, most chinks give free shipping for things these small. With the money saved on shipping you could probably buy a whole lifetime supply of gates
You can also order samples for most things directly from TI with free shipping
This
what said
it's the same story with usb sticks, you don't order them by piece, but by kg
Aliexpress
Literally 1-2 dollar a pop including shipping
Same with Microchip products
It's not that bad.

This.
ever heard about /csg/?
the Chinese goverment covers almost all international shipping for items under 2kg
Serious question, why would you buy individual logic gates when a whole microcontroller is like 50 cents and sips almost no power?
Because you touch you'reself at night
Are you 5?
none of those places supply 74ahc00n
only mouser does
Why do you need logic gates? Just get a CPLD.
1. ive never used cpld
2. i need this
Can't you just get a more popular NAND IC?
E.g. the 74hc20
Wat country?
Here in Holland a bunch of electronics enthusiasts made a website were you can order from farnell with his account
i could do with 74x00 but i needs to be PDIP
Why do Russians seemingly buy EVERYTHING online from China?
AliExpress is like 90% Russian reviews for everything.
CD4012BE maybe?
They're right next to each other.
Since when cant everybody order from farnell ? .... nl.farnell.com ?
Just be thankful you don't need exotic analog ICs like 8-pole filters and logarithmic amplifiers cause that shit costs $10-20 in one off quantity plus shipping.
Don't believe me? Check digikey. TL-441 log amp is $6.58 in one off quantity and the MAX274 8th order configurable low-pass, high-pass, band-pass filter is $17.61 per IC. Now yeah that's only for the 24-DIP variant and if I went SOIC it would be around $11 but then I can't easily breadboard it without making a PCB and and getting some headers. That alone has exceeded the cost of the DIP IC.
In Germany there is similar shit for Mouser.
i bet this fucking guy says the same shit to everyone who doesn't care just to show off how much he knows about the "intricacies" of dealing with ICs
If you need lots of expensive exotic ICs then your design is shit.
It's not as old the 7400 series
How about I don't want to do 8-pole filters with regular op-amps, resistors, and capacitors which will not only take up a lot more board space but will also need additional trimmers to ensure I get the frequency response just right and keep passband ripple to a minimum you moron.
Why don't you use a DSP like someone from this century?
hmm. never really looked into anything other than 7400 series.
TI?
Link?
Cause I am complete shit at programming. Give me analog electronics and I'm fine, and even some discrete digital stuff too, but microcontrollers and FPGAs is over my head.
Getting a PIC32 to output to 7-segment displays took me several days of work and a lot of frustration though a lot of that was because the dev board for it was supposed to be more Arduino friendly and work with the Arduino IDE but it didn't like me trying to address registers directly like how I learned how to do it. Like if I wanted the pin corresponding to PORTB3 high I'd do it like PORTB b00000100 vs how Arduino likes you to do it digitalWrite(7) = HIGH where physical pin 7 on the IC corresponds to PORTB3. I found the whole thing convoluted and nonsensical. It's making things more difficult for technical people in order to appeal to non-technical people.
There's some hardware you can directly program with Simulink.
I'll have to look into that. I know I won't get away with avoiding DSP forever.
texas instruments, you dumb fuck
As a fellow EE, whenever you get to the "No I NEED this gate/part/value" it's prime time to step back and really consider your design.
how else am i gonna debounce some shit switches without software
Don't you want a Schmitt trigger for that?
Mostly because of cheap shipping and no tax. Russia still have zero import tax for parcels up to 1000euro. But it works only with "russian post" which is used by ali.
Many european/american shops are offering only dhl international or doesnt ship to russia at all. So dhl is expensive AF, mail forwarder services are not cheap too and on top of that you get a 200$ tax-free limit, broker-fee and much more chances to be found breaking one of the many dumb import rules.
But those good times are coming to an end. Putin desperately needs money so right after his fourth "reelection" fax-free limit will be dropped to 20eur.
>tfw just started my EE degree and read through this thread
Am I in for a world of pain designing circuits?
why would i need schmitt triggers
>Like if I wanted the pin corresponding to PORTB3 high I'd do it like PORTB b00000100 vs how Arduino likes you to do it digitalWrite(7) = HIGH where physical pin 7 on the IC corresponds to PORTB3.
That's because Arduino has to work for many different MCUs. Some AVR might use an 8bit int register, some ARM a 32bit int.
If you don't care about it being portable you can just use the registers directly, it's just C++ after all.
You can also program an Arduino with avr-gcc directly and ignore the IDE.
If you use an RC circuit for debouncing:
labbookpages.co.uk
im using s-r latch to debounce since i read that it's the best
Why don't you just get an SR-latch IC? Like a CD4044.
...
Its like $5
You'd like that, wouldn't you?

don't get what is the big deal.
ali links aren't filtered you don't need to censor them
http links used to be filtered on /d back when moot felt in charge.
straight up, this is not true. either your job is really easy or you haven't had a project that's more complicated than displaying digits.
i do agree that there will always be a better solution, but that doesn't mean you won't get cornered
You are aware that you need a 2 position button, not just a regular ass connect/disconnect micro-switch
what do you mean?
