I'm trying to build a simple astable multivibrator using a [CD4047](https://www.ti.com/lit/ds/symlink/cd4047b.pdf). I try to demonstrate using 3 LEDs on the OSC, Q, and Q` pins. Following is the circuit I built (copied diagram):

The only difference I have is that I have 220 Ω as the LED driver resistor and Pin 6 is connected to Vdd.

I can only see the OSC LED blinking at about 5 Hz. The Q` is always on, Q is always off after just one blink at the startup..

I tried with two CD4047s (purchased from the same store).

What could be the problem?
