74141 DATASHEET PDF

Samugis On the right side you also see 10 transistors which only have the job to drive the LEDs and the inputs of the controller. The russian types are either orhigh serial numbers arelow serial numbers are The datashet I have I will use for my next projects. I also found out what I wrote above in the section about the russian tubes. My other projects took away a lot of time, so I decided to give it to a friend of mine to do the coding. So I added a IC.

I also found out what I wrote above in the section about the russian tubes. My other projects took away a lot of time, so I decided to give it to a friend of mine to do the coding.

So I added a IC. All are tested now. My friend did the coding this time had little time The ATmega is totally cool!!! You only have to put in the test-IC. Check the different truth- charts!!! Truth Table for the, A and B Chip. The ZM tube is driven with 2mA current. The V plus tube and resistors with the voltage dividers make it possible to detect a eatasheet high leakage current in case the IC is defective.

Ok, lets go to the Sketch I made for my tester. I got daatasheet hints from the Neonixies Gang that in some cases a defective may leak at the outputs. Truth Table for theand A Chip. Related Posts.

Remenber that te russian types are marked like this orange! The russian types have high "off" voltage approx V , so the efficiency is much better, and the "Blue Spot" problem can not occur e. Just some words: The 2. On the right side you also see 10 transistors which only have the job to drive the LEDs and the inputs of the controller. The ATmega is totally cool!!! I will use it for all my clocks in the next future because you need no other parts around it!
