Hi all

Question, because of sucking christmas, i need one part only, to finish my 4-pole.

So, is this one good ? http://www.conrad.ch/ce/de/product/151572/High-Speed-CMOS-74-HCT-XXX-IC-Texas-Instruments-CD-74-HCT-4051-E-Gehaeuseart-DIP-16-Ausfuehrung-Analoger-Multi-Demultiple/SHOP_AREA_17311&promotionareaSearchDetail=005#

Thanks for your help…

yes TTL will work fine, Shruthi operates within 5V range too.

#3

ok fine… Thanks

Another question…

If i use this one, will this one work with the digital board? (Q1)

Nope its SMD, you need a "thru hole componen"t:http://www.conrad.de/ce/de/product/155192/Quarz-HC494H-Serie-Crystal-EuroQuartz-20000MHZ-HC494H-30504018PFATF-Frequenz-20000000-MHz-B-x-H-x-T-1026-x-3/1207072&ref=list

Make shure you use 18pF Caps as stated in the Datasheet of the Quartz

Hi fcd72… Supper! Thank you… It’s a little bit a bad site… not so good like farnell or else…

PS: Next month if you have this nice cases, i will be there… :wink:
PS2: Sad that the shop is closed for PCB Polivoks… Now i have holidays like mutable… :frowning:

Why don’t you order from reichelt.de - for quartzes you will need slightly bigger caps (see the data sheet)

#7

yes the reichelt quartzes work good with 27 or 33pF.
Conrad are good at not carrying anything and pretending polystyrene don’t exist. also i have the impression their supposed free shipping has already been double compensated in their component prices.
rant over :slight_smile: just got a reichelt parcel yay

ok… then i go to reichelt.! reichelt is nice! fast shipping… faster than the bad switzerlands farnell.ch realy sad service in the last 40 days!
