Other Parts Discussed in Thread: SN74LVC1G123
I am trying to understand the pulse width accuracy for the TLC555 at Vcc=5V. I tried using the Vit (Threshold voltage) range stated in the datasheet (2.7 MIN to 3.9 MAX), but results show the timer to be unusable, An 18% error in threshold which yields a much higher error in pulse width due to the exponential charging from 0V to the threshold. A simple resistor divider internal to the part sets the threshold so it should be very accurate. What am I missing??
