At 25C and at 10v supply voltage, maximum quiescent device current Idd max is 10uA.
Distorted Sine output from Transformer 8. You stated “Q output of the CD shows connected to Vcc shorting the output “. It is probably in stock at your local NXP distributor.
I needed the schematic too so I reversed engineered it. General electronics theory eg: Become a Redditor and subscribe to one of datashete of communities.
Commercial stuff selling, paid work etc. It is an old part but still in production. You should be able to connect your NC alarm relay in series with 12v power and VCC on the 2 conductor terminal. PNP transistor not working 2.
They may give the voltage but not the current, or where you need to know the size, that’s omitted from the description. Also for advice on electronic component specs pinout, equivalents, timing, signal levels etc. All I see are whiners who want everything handed to them so they don’t have to think or learn and now an inconsiderate person who overstates a problem on the board and makes a real obvious error not even getting his criticism right.
It’s hard to trace through that board. First, check out our list of national and dstasheet suppliers. Meta Related to this subreddit.
I wanted to use this HC relay with the Roiscok but datashet I am thinking I need to abandon one or both of them. Synthesized tuning, Part 2: Reading through the datasheet I found a Digital Timer Applicationthat datashete the circuit I have to design. Use this tag if you need help sourcing electronic components or parts related to a circuit build or repair. What is the function of TR1 in this circuit 3.

datazheet What is this Identifying an electronic component in an electronic assembly. Thanks Caspa-B, I really appreciate you taking the time to say thanks. Part and Inventory Search. Dec 242: This chip is suitable for high voltage 20v supply.
Theory General electronics theory eg: High voltages are potentially dangerous.
I wish I could pull the schematic I posted off. CD pin 9 gives you the flexibility to create exactly what you want. PIR sensor module etc May be datasheef can provide the trigger pulse after power up.
