I use the SN74LVC04ADGVRG4 to convert the frequency that I take with quartz resonator. Then the data from the SN74LVC04ADGVRG4, I was treated to a microprocessor pic16 and get a working frequency of the quartz resonator. If a little chip heating of the case, it begins to affect the outgoing data and introduce errors in the calculated numbers of frequency.
Ambient temperature of 22 ° C, the body I warmed to 30 ° C. Why is a strong influence on the result of SN74LVC04ADGVRG4 change temperature.
How can this be avoided.
