I could do it with a quad NOR gate, but that is a 14 pin DIP package that needs 12 wires connected when you include tying unused inputs to ground. That takes a lot of room on my breadboard and a lot of time to set transisotr.

See details for additional description. The base and collector are reversed from the 2nA? What is it about switching transistors that makes them unsuitable for a circuit like this? These are loose parts that I’ve collected in various electronics kits and trznsistor through the years.

DuncanC I would say that in the diagram where I drew the red box the flat side is facing the reader.

Andy aka k 10 So is that a rule of thumb, make r2 10x the r1 value? Also, I would use a much lower resistor instead of k, maybe 10k.

Are you sure that a it is an NPN transistior b with a sufficient B current amplification factor and c transisyor you connected it correctly? Golden rule – always read the data sheet and if you can’t find one then don’t assume. Post as a guest Name. Email Required, but never shown. It’s maddening that the pinouts aren’t the same.

If so, note the pins red line – they are not the standard pin-out with base in the centre like the 2NA: The lowest-priced brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable. I’m having a little trouble understanding the pinout diagram from that data sheet. Hey try it both ways or even test it with a multimeter for diode between base and collector and base and emitter. Why can’t the industry standardize on one pinout convention for a given type of component and package?

At Dalbani we like to differentiate between new, previously installed parts usedand parts made by 3rd party manufacturers. This is the price excluding shipping and handling fees a seller has provided at which the same item, or one that is nearly identical to it, is being offered for sale or has been offered for sale in the recent past. I just swapped the base and collector in my breadboard, and now the C works in place of the A.

I don’t know for sure what these are.

How to invert a digital signal The circuit looks like this: Let us fix the problem for you. Exactly 10x, or 10 or less? Be the first to write a review. So the leftmost pin is the emitter, the middle is the collector, and the rightmost pin is the base? Sign up using Email and Password. If the pins are not in standard order that would certainly explain it though! I’ve been working with an Arduino lately, and building various breadboard circuits. Show More Show Less.

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