Other Parts Discussed in Thread: SN74LS221
We are using CD74HC221 monostable multivibrator for our one of the project. We are using external capacitor (10uF) and resistors (100K) for 800mS pulse width calculated as per formula provided in datasheet. But i am not getting the outputs as expected (IC is not responding for input).
When i am using 10uF and 50K resistor, i am getting 400ms pulse width as per datasheet. SPDT switch output is given to CD74HC221. Let me know the suggestion to get output.
