Duncan C 1 10 I’ve been working with an Arduino lately, and building various breadboard circuits. I don’t know for sure what these are. How to invert a digital signal. The base and collector are reversed from the 2nA? What is it about switching transistors that makes them unsuitable for a circuit like this?

We have ratings, but no written reviews for this, yet. Exactly 10x, or 10 or less?

Andy aka k 10 It’s maddening that the pinouts aren’t the same. 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.

I built an inverter based on this thread: How to invert a digital signal The circuit looks like this: Golden rule – always read the data sheet and if you can’t find one then don’t assume. I could not find datasheet for the C Sign up using Trabsistor and Password.

Are you sure that a it is an NPN transistior transisto with a sufficient B current amplification factor and c that you connected it correctly? A simple example was to build a transistor based inverter for a project involving baud serial combination at 5v.

Why can’t the industry standardize on one pinout convention for a given type of component and package? Skip to main content. I understand that a “real” CMOS inverter is a better choice for this application, but bear with me.

Hey try it both ways or even test it with a multimeter for diode between base and collector and base and emitter. That takes a lot of room on my breadboard and a lot of time to set up. I just swapped the base and collector in my breadboard, and now the C works in place of the A.

These are loose parts that I’ve collected in various electronics kits and projects through the years.

Might be a silly transistpr but did you check the pinout of the switching device?

I thought switching transistors were tuned for very “snappy” response that tends to be either fully on or fully off. So is that a rule of thumb, make r2 10x the r1 value?

Why won’t a switching transistor work in this circuit Ask Question. Also, I would use a much lower resistor instead of k, maybe 10k. Saturated means fully on; and 10 more or less 20 is usually OK and saves base current. So the leftmost pin is the emitter, the middle is the collector, and the rightmost pin is the base?

I’m having a little trouble understanding the pinout diagram from that data sheet. 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.

If so, note the pins red line – they are not the standard pin-out with base in the centre like the 2NA: Sign up using Facebook.
