Feb 26, 9. In case of any inconsistency or con? Make a small pcb for it and use a 0. The resistor at pin 11 should be about 10 times the value of the timing resistor but yours is way too high. The format of datashset data sheet has been redesigned to comply with the new identity guidelines of NXP Semiconductors.
Have you used this one? No, create an account now. Feb 24, 3. For more information, please visit: Posted by ro in forum: It uses the same pins 10 and 11 as the RC oscillator. Do you already have an account? Recommended operating conditions Table 4. The scope is at 2. Feb 25, 8.
It will work this way? There are many datasheets for the osc The product status of device s described in this document may have changed since this document was published and may differ in case of multiple devices.
The resistor at pin 10 is the timing resistor but yours is at pin You don’t show pin 8 tied to ground, and pin 12 is floating.
Feb 24, 5.
Plastic or metal protrusions of 0. A practical value for R2 is 2. A short data sheet is intended for quick reference only and should not be relied upon to contain detailed and full information.
What if I use a PLL to stabilize the oscillation?
Feb 24, 4. They float up to the logic level changeover point and oscillate.
Rt must be larger than the ON resistance in series with it, which typically is ? Does it live up its predecessor?
I made the modifications that you proposed. In the last experiment I tried to use a ceramic capacitor. You would need a frequency counter to see what the actual output frequency was, and change components to get it to the correct frequency.
