If the pins are not in standard order that would certainly explain it though!

Save on Transistors Trending price is based on prices over last 90 days. So is that a rule of thumb, make r2 10x the r1 value?

Thank you very much. Also, I would use a much lower resistor instead of k, maybe 10k. Duncan C 1 10 d1740 See details for additional description. How to invert a digital signal.

Saturated means fully on; and 10 more or less 20 is usually OK and saves base current. Exactly 10x, or 10 or less? Home Questions Tags Users Unanswered.

I built an c140 based on this tansistor I don’t know for sure what these are.

I understand that a “real” CMOS inverter is a better choice for this application, but bear with me. Sign up or log in Sign up using Google. The base and collector are reversed from the 2nA? We will do our best to get back to you as soon as possible. The “off” amount and percentage simply signifies the calculated difference between the seller-provided price for the item elsewhere and the seller’s price on eBay.

I’ve been working with an Arduino lately, and building various breadboard circuits.

Are you sure that a it is fransistor NPN transistior b with a sufficient B current amplification factor and c that you connected it correctly? Golden rule – always read the data sheet and if you can’t find one then don’t assume. I just swapped the base and collector in my breadboard, and now the C works in place of the A.

Might be a silly question but did you check the pinout of the switching device? I could do it with a quad NOR gate, but that is a 14 pin Transjstor package that needs 12 wires connected when you include tying unused inputs to ground.

Email Required, but never shown. Why can’t the industry standardize on one pinout convention for a given type of component and package? I’m having a little trouble understanding the pinout diagram from that data sheet.

A trnasistor example was to build a transistor based inverter for a project involving baud serial combination at 5v.

So the leftmost pin is the emitter, the middle is the collector, and the rightmost pin is the base? How to invert a digital signal The circuit looks like this: Is the flat side facing up in the red box above?

What is it about switching transistors that makes them unsuitable for a circuit like this? DuncanC I would say that in the diagram where I drew the red box the flat side is facing the reader.

If so, note the pins red line – they are not the standard pin-out with base in the centre like the 2NA: That takes a lot of room on my breadboard and a fransistor of time to set up.

I thought switching transistors were tuned for very “snappy” response that tends to be either fully on or fully off.
