Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at To participate you need to register.

Here is a graph of the gain and frequency response of a CD or a 74C04 Adtasheet inverting amplifier:. These and the CD are logic inverters that are always Un-Buffered.

Replacement Transformer Started by ncag Today at 7: Hero Banned Aug 14, Interestingly enough, each stage is doubled — I am guessing for better current supplying capacity at the outputs. Trying to use a 2n dafasheet to trigger an alarm panel. It also happens to be where the ground trace connects. No wonder these things last forever on a battery. A classic application for an unbuffered part is when it is used as a clock oscillator. Since there is no hysteresis, the alarm will shut off the moment contacts stop touching water.


R1 keeps gate of the FET pulled low, to keep it off. None of my meters could resolve it even when in uA range. Is the answer 60?

Nice attention to details. The CD is not recommended by Texas Instruments.

Media New media New comments Search media. Articles Top Articles Search resources. When alarm is on, the current jumps to datashete 11mA. Today we have a somewhat vintage teardown.

Could the frequency of the sound be changed to lets say 1kHz? Do you have any info on the buzzer, such as a part number? That app note was a great read! Your email address will not be published. Welcome to our site! CD is so old, the datasheet is still cd4069ubf Harris. Keep linking good, informative sources.

Not much in here and sure looks like the eighties! This alarm has a pretty simple task- sit somewhere quietly and watch for water leak.


It was fed the signal from a switched-capacitor lowpass filter IC and both were together in a feedback loop. The rainwater comes into quadrant III, and reaches the finished room before it gets to the drain or the sump.

While in standby, the only power drain is the leakage through C1 and Q1. I made some fairly low distortion 0.

Oh well, at least the part itself is connected correctly. If they are used as a linear amplifier then they self-bias at an output voltage too low and with low gain. Another strain relief on the battery wires to go over case plastic. It just shares C1 with the rest of the board. For a better experience, please enable JavaScript in your browser before proceeding. The CD is recommended instead if it has a single supply voltage.
