Test circuit for measuring switching times Table 8. Feb 24, 5. Help Using a As an Oscillator! The latest product status information is available on the Internet at URL http: External component connection for a crystal oscillator Fig It cannot be used as supply pin or input. 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 datashheet of this data sheet has been redesigned to comply with the new identity guidelines of NXP Semiconductors. Sep 11, 0.

Does the IC have a supply bypass capacitor? This document supersedes and replaces all information supplied prior to the publication hereof.
In consideration of accuracy, Ct must dataeheet larger than the inherent stray capacitance. The cmos oscillator is very stable if it has a regulated power supply and it does not pick up interference shielded in a grounded metal box.
A practical value for R2 is 2. Feb 26, 9. The stray capacitance C2 should be kept as small as possible. Quote of the day.
For more information, please visit: However is my circuit correct now for a 1MHz oscillator? Could anyone help me please? However, NXP Semiconductors does not give any representations or warranties, expressed datasheey implied, as to the accuracy or completeness of such information and shall have no liability for the consequences of 774hc4060 of such information.
Have you used this one? I tried the experiment with the cited values and the circuit still not oscilatting When I measured in the Q7 pin the oscillation was more clear than the olther pins The counter advances on the negative-going transition of RS. 74jc4060 to make changes — NXP Semiconductors reserves the right to make changes to information published in this document, including without limitation speci?
Feb 23, 2. Make a small pcb for it and use datashedt 0. For detailed and full information see the relevant full data sheet, which is available on request via the local NXP Semiconductors sales of? Rt must be larger than the ON resistance in series with it, which typically is ? The 74HC can use a 1MHz crystal for accuracy.
Feb 25, 8. The resistor at pin 10 is the timing resistor but yours is at pin All referenced brands, product names, service names and trademarks are the property of their respective owners.
Timer – Posted by Bernard in forum: I made the modifications that you proposed. For starting and maintaining oscillation a minimum transconductance is necessary, so R2 should not be too large.
MC54/74HC datasheet & applicatoin notes – Datasheet Archive
Apr 26, 3, 1, This document contains data from the preliminary speci? Plastic or metal protrusions of 0. Feb 26, Feb 24, 6.
You do not add fatasheet 1pf capacitor, it is stray capacitance and must be kept as low as possible. What if I use a PLL to stabilize the oscillation? There are many datasheets for the osc A short data sheet is intended for quick reference only and should not be relied upon to contain detailed and full information. Post your schematic and show the supply voltage. Does it live up its predecessor?
