CDUBE datasheet & applicatoin notes – Datasheet Archive
Q1 along with the forward cd4069ubs of D1 determine minimum voltage the circuits operates at- around 4V, well beyond a typical 9V battery end of life. The buzzer driver uses the six inverters to create an oscillator with a frequency of around 3.
R1 keeps gate of the FET pulled low, to keep it off.
Trying to use a 2n mosfet to trigger an alarm panel. Thread starter Hero Start date Aug 13, It looks like I’ll have to order some CDs or 74C04s then.
What’s the difference between the CD4009 and CD4069?
I drew the chip U1 as seven parts for clarity: With sufficiently conductive fluid touching the two electrodes, the gate of Q1 gets pulled up and it turns on. A classic application for an unbuffered part is when it is used as a clock oscillator. The CD is not recommended by Texas Instruments.
Selfdischarge will probably be the main driver of that. The rainwater comes into quadrant III, and reaches the finished room before it datassheet to the drain or the sump. That app note was a great read!
Another strain relief on the battery wires to go over case plastic. The lowpass filter reduced the 3rd harmonic distortion caused by the compression. Datasheets, Manuals or Parts. Luckily it does not take much to make one on a design this simple. Media New media New comments Search media.
Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Has anyone here tried using this water alarm as more than just an alarm? The enclosure is not sealed and if water level keeps rising past the sensing compartment, there is no guarantee that the alarm will stay functional. They also might melt. No wonder these things last forever on a battery. I made some fairly low distortion 0.
I’ve read through the datasheets and I’m ashamed to say I’m stuck. First time I have seen the uCurrent being used as well. It appears Source and Drain are swapped in silk.
CDUBE CD Hex Inverter IC
Very nice tear down and very in depth. They sink 50mA but source only 8 ma with a 10V supply and an output voltage of 5V.
Today we have a somewhat vintage teardown. You must log in or register to reply here. Its great you even were able to build the schematic from it. And now on to the schematic. Leave a Reply Cancel reply Your email address will not be published. The CD parts that are for sale these days always have a U after the number, that is CDU and this datashheet important. What we have here is two essentially independent sections. Replacement Transformer Started by ncag Today at 7: A Cmos inverter makes a pretty distorted output because its output compesses the signal near the rail voltages.
Forums New posts Search forums. Interestingly enough, there is not even a dedicated decoupling cap on U1. The Dahasheet has symmetrical source and sink currents but not as high as 50mA.
The bottom one is just a driver for the buzzer.
