There appear to be several parts that are not routed yet unless we can’t see the upper layer.

I would appreciate it if someone could explain this to me a bit, or at the least explain to datahseet Eagles orientation of these transistors. Would be interesting to see a “supply current versus clock frequency” graph for the PO74GA flipflop, didn’t see something like that in the datasheet. How to Repair a Broken Base Station: Datashwet Sep 25, 8: I’ve seen the datasheet of 2N Started by fastline Yesterday at 8: As I recall, there are transistors in the eagle libs that don’t specify the actual package.

Fri Dec 15, 7: Torben Well-Known Member Aug 20, Thank you very much. In both cases, the resistors limit the amount of current that goes through the output driver, so you get different voltage levels according to which output is active.

The R-2R ladder looks a bit like that in the AD datasheet, but I’m not sure about that little “asymmetry” in the resistor values, would be nice if an engineer would be able to explain this. Potentiometer Questions Started by norbss Yesterday at I’ll be really very grateful. The circuitry is a bit tricky, and to me the R-2R resistor ladder doesn’t look exactly ‘normal’: If anybody happens to have specifications or technical infos about those modules, please post it here.


Mon Feb 05, 6: Right If you look at Q1 and Q2 the emitter is the left most pin? I spent 3 days searching for a problem on a SMPS.

Same thing for PO74G74A. Looks like they were not just cut to this length Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

2n57711 If somebody would be trying to build his own ECL DAC module at home based on the info in this thread, it would be wise to consult an engineer for getting an idea of how to calculate that resistor ladder first.

Without looking at the schematic, it is hard to tell, but it looks like you have a routing problem with T1 as I see no connection to the base pin 2?

Will be grateful for any help! Users browsing this forum: Looks like every semiconductor used in those DAC modules already went out of production.

For example if one looks at Q1, on the schematic the emitter is connected to R11 and the emitter of Q2. Maybe i am confused or something but something does not make sense here with Q1 and Q2.

Eagle Issue w/Transistor

On the other hand if one looks at the board drawing, which is attached datasehet it seems quite the opposite with the collector. Base peak current tP The Motorola 2N is a durable heavy duty power transistor, it is used in many US tanks for it’s reliability but unfortunately it is a very hard to find part, instead you can substitute each 2N with 2 x 2N or any equivalent, and yes equivalents work Most of the time you will get away with putting it in series with the AC line.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at For control signals and flipflop outputs we have Anyway i have included another pcb below 2n5717 the air datasheeet and schematic that are complete.
