When I measured in the Q7 pin the oscillation was more clear than the olther pins What else could be wrong? Does it live up its predecessor? Feb 23, 1. Contact information For more information, please visit: What type of capacitor should I use?
The output will probably be close to 1 MHz. Feb 23, 2.

The format of this data sheet has been redesigned to comply with the new identity guidelines of NXP Semiconductors. Apr 20, 15, Posted by ro in forum: Feb 27, The 74HC can use a 1MHz crystal for accuracy. No, create an account now. You don’t show pin 8 tied to ground, and pin 12 is floating.
RC oscillator frequency as a function of Rt Fig A practical value for R2 is 2. You would need a frequency counter to see what the actual output frequency was, and change components to get it to the correct frequency.
However is my circuit correct now for a 1MHz oscillator?

Could anyone help me please? Legal texts have been adapted to the new company name where appropriate. Applications — Applications that are described herein for any of these products are datashwet illustrative purposes only.
The datasheet of the 74HC shows that its minimum allowed timing capacitor is 50pf. However, I tried this configuration datadheet is annexed in the image below and I cannot get any oscillation at all.

Apr 26, 3, 1, Post your schematic and show the supply voltage.
The stray capacitance C2 should be kept as small as possible. Are you 74h4060 auto triggering or internal? The resistor at pin 10 is the timing resistor but yours is at pin NXP Semiconductors does not give any representations or warranties as to the accuracy or completeness of information included herein and shall have no liability for the consequences of use of such information.

Mar 1, Feb 28, Waveforms showing the master reset MR pulse width, the master reset to output Qn propagation delays and the master reset to clock Datassheet recovery time Table 7. Do you already have an account? You do not add the 1pf capacitor, it is stray capacitance and must be kept as low as possible.
Yes, my password is: The oscillator may be replaced by ddatasheet external clock signal at input RS.
