The latest product status information is available on the Internet at URL http: 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 dayasheet or completeness of information included herein and shall have no 74h for the consequences of use of such information. There are many datasheets for the osc However, I 74hc this configuration that is annexed in the image below and I cannot get any oscillation at all.

Example of a RC oscillator The recommended values for these components to maintain agreement with the typical oscillation formula are: External component connection for a crystal oscillator Fig It cannot be used as supply pin or input.

They float up to the logic level changeover point and oscillate. What is wrong with my circuit? For detailed and full information see the relevant full data sheet, which is available on request via the local NXP Semiconductors sales of?

Posted by ro in forum: The counter advances on the negative-going transition ratasheet RS. Limiting values are stress ratings only and operation of the device at these or any other conditions above those given in the Characteristics sections of this document is not implied. Feb 23, 2. Does the IC have a supply bypass capacitor?

The function of R2 is to minimize the in? The format of this data sheet has been redesigned to comply with the new identity guidelines of NXP Semiconductors. For starting and maintaining oscillation a minimum transconductance is necessary, so R2 should not be too large. The cmos oscillator is very datashfet if it has a regulated power supply and it does not pick up interference shielded in a grounded metal box.

The resistor at pin 11 should be about 10 times the value of the timing resistor but yours is way too high. Right to make changes — NXP Semiconductors reserves the right to make changes to information published in this document, including without limitation speci? This document supersedes and replaces all information supplied prior to the publication hereof.

Dynamic characteristics Table 6. Quote of the day. Static characteristics Table 5. I remade the experiment and I am getting a lot of jitter in this oscilattor. However is my circuit correct now for a 1MHz oscillator? A practical value for R2 is 2. Plastic or metal protrusions of 0. The datasheet of the 74HC shows that its minimum allowed timing capacitor is 50pf.
