The resistor at pin 10 is the ddatasheet resistor but yours is at pin Ptot derates linearly with 5. In consideration of accuracy, Ct must be larger than the inherent stray capacitance. Feb 25, 8. You don’t show pin 8 tied to ground, and pin 12 is floating.

The format of this data sheet has been redesigned to comply with the new identity guidelines of NXP Semiconductors. Could anyone help me please?

You would need a frequency counter to see what the actual output frequency was, and change components to get it to the correct frequency. The latest product status information is available on the Internet at URL http: Feb 23, 2. Sep 11, 0.

This datasheet contains data from the preliminary speci? I tried the experiment with the cited values and the circuit still not oscilatting Do you already have an account?

I remade the experiment and I am getting a lot of jitter in this oscilattor.

Feb 26, 9. Waveforms showing the master reset MR pulse width, the master reset to output Qn propagation delays and the master reset to clock RS recovery time Table 7. For starting and maintaining oscillation a minimum transconductance is necessary, so R2 should not be too large. A practical value for R2 is 2. Ptot derates linearly with 4. Feb 24, 5.
