No, create an account now. Yes, my password is: Apr 20, 15, Could anyone help me please?

Do you already have an account? Does it live up 74hc400 predecessor? The resistor at pin 11 should be about 10 times the value of the timing resistor but yours is way too high.

You don’t show pin 8 tied to ground, and pin 12 is floating. For starting and maintaining oscillation a minimum transconductance is necessary, so R2 should not be too large. Due to tolerances in the resistors and capacitor, it may be somewhat off. The cmos oscillator is very stable if it has a regulated power supply and it does not pick up interference shielded in datashedt grounded metal box.

The circuit for the crystal oscillator is in the datasheet. Applications — Applications that are described herein for any of these products are for illustrative purposes only.


Plastic or metal protrusions of 0. It should also go to ground, as floating inputs always create problems. Limiting values Table 3.
