Q1 along with the forward drop of D1 determine minimum voltage the circuits operates at- around 4V, well beyond a typical datasheer battery end of life.

I need to get one of those. The lowpass filter reduced the 3rd harmonic distortion caused by the compression. The rainwater comes into quadrant III, and reaches the finished room before it gets to the drain or the sump.
The design is nicely compartmentalized, with separate areas for sensor wiring, battery and electronics. I’ve read through the datasheets and I’m ashamed to say I’m stuck.
CD is so old, the datasheet is still from Harris. The CD has symmetrical source and sink currents but not as high as 50mA.

No wonder these things last forever on a battery.
Dattasheet much in here and sure looks like the eighties! Is the answer 60? Has anyone here tried using this water alarm as more than just an alarm? Trying to use a 2n mosfet to trigger an alarm panel. Thread starter Hero Start date Aug 13, Keep linking good, informative sources. C2, I guess, is to even out any voltage spikes when the gate changes state? Datasheets, Manuals or Parts. None of my meters could resolve it even when in uA range.
It looks like I’ll have to order some CDs or 74C04s then. If they are used as a linear amplifier then they self-bias at an output voltage too low and with low gain. Rumor has it these last forever on a nine volt battery!
It just shares Fd4069ube with the rest of the board. Very nice tear down and very in depth. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at A Cmos inverter makes a pretty distorted output because its output compesses the signal near the rail voltages.

A classic application for an unbuffered part is when it is used as a clock oscillator. It works well as a linear amplifier. Today we have a somewhat vintage teardown. These and the CD are logic inverters that are always Un-Buffered.
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.
