Hi,
I designed a circuit in Tina by using SN74LV123A monostable multivibrator. In this design I expect 50ms tw at the output pin(Q) of SN74LV123A. According to tw=K*R*C formula I used 50k resistor and 1u capacitor to obtain 50ms tw at the output. But I obtain approximately 64 ms at the output and this value is not useful for my design. I used below formula to calculate tw value.
I used 2 SN74LV123A in this design. U8 is negative edge detector and U5 is positive edge detector. At the outputs(DIR and ROT) I expect 50ms pulse.According to formula Tw=K*R*C K=1, R=50K, C=1U Tw=50 ms
According to simation result I obtain approximately 64 ms pulse duration.Could you help me how I can obtain 50 ms pulse at the outputs?
