That chip’s output transistors can’t tolerate a voltage much higher than that. What’s the cathode voltage when switched off? What’s the purpose of the anode resistor? Use of this site constitutes acceptance of our User Agreement and Privacy Policy.

I like Peter’s better because it’s a little more straight forward and he explaines every section very well. Well that is a close one on this uC.

If the voltage try’s to rise higher than that, the zener will start conducting, and current will flow. Description Want to drive a Nixie? Do you meet all criteria? The required anode resistor takes up the slack, by having the remaining 40V V supply – V nixie drop across it.

Lets use a shift register. Instead of a bunch of separate transistors, you can use a TD or an SN which have 8 or 7 transistors in one DIP package, which saves a lot of wiring.

Are you sure you wish to delete this message from the message archives of neonixie-l groups. How can I notify you, if your email address doesn’t work? I really find some old which don’t work or leak. A subreddit dedicated to news, articles and general discussions related to the field of electronic engineering. After building that once, you’ll decide that a microcontroller design is less work and more flexible.

One Nixie Digits and Dot: Want to add to the discussion? Rather than replicating existing designs, he decided to build his project from scratch, learning new techniques and tricks while improving his design as he progressed.

Nixie driver ICs 74141

When holding the button for longer than one second you come back to the free- running mode. If the difference is bigger than 60V, then you should not use the western version of the Don leaves it up to the reader to follow along and build the example circuits so as to be able to see them working first hand.

I’ve read with interest your post on driving the cathodes in k155od1 ways. Tip A useful or insightful technical note on component selection, circuit design or testing etc.

How Does it Work?: The KID1 and the 74HC

You might simply connect on transistor to one digital IO of your favorite microcontroller. These are mostly intended to connect to the inputs dataeheet chips of the same ‘ilk’.

In this fast-paced time of speedy processors, and k155idd1 sorts of things only dreamed of when those books were written, one can still get right down to each binary bit, and where it goes, and exactly what it does. Well, most logic chips 74xx, 4xxx, Just tie all the emitters together, and hook them up to a single emitter resistor 1Kwith its other leg tied to Gnd.

Your email is included with the abuse report. I guess this is what I get for writing rants late at night: Thanks to you all, Frank. When using a more modern controller running with 3. Because of this, all we care about is the sinking capacity because of our usage in this datssheet the transistor should be able to handle the load fine, voltage is irrelevant.

What’s the IO output and supply voltage? You can also clock in 8 zeros.

Crosscheck the recommended values.
