Quote of the day.

A practical value for R2 is 2. 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. Short data sheet — A short data sheet is an extract from a full data sheet with the same product type number s and title. Are you using auto triggering or internal?

MC54/74HC datasheet & applicatoin notes – Datasheet Archive

I tried the experiment with the cited values and the circuit still not oscilatting Yes, my password is: 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. For starting and maintaining oscillation a minimum transconductance is necessary, so R2 should not be too large.


However, I tried this configuration that is annexed in the image below and I cannot get any oscillation at all. The resistor at pin 11 should be about 10 times the value of the timing resistor but yours is way too high.

Make 74hc460 like this: There are many datasheets for the osc For more information, please visit: 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. They float up to the logic level changeover point and oscillate.

Your name or email address: Plastic or metal protrusions of 0. Does it live up its predecessor? Does the IC have a supply bypass capacitor?

The counter advances on the negative-going transition of RS. External component connection for a crystal oscillator Fig Feb 24, 4. Do you already have an account?

It cannot be used as supply pin or input. The datasheet of the 74HC shows that its minimum allowed timing capacitor is 50pf.

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. Help Using a As an Oscillator! Exposure to limiting values for extended periods may affect device reliability. You do not add the 1pf capacitor, it is stray capacitance and must be kept as low as possible. This document supersedes and replaces all information supplied prior to the publication hereof.
