I need to implement a one-shot stage to generate a negative voltage pulse (0 to -3V) lasting around 2 usec, triggered by a TTL pin of a micro. Dual PSU (+/- 5V) available.
Been considering an LM311 connected between 0 and -5V. I got just one! of those comparators for the week end and I fear to destroy it in any uncontrolled test. Additionally I cannot see how to trigger it with a positive voltage and even more as a one shot.
Reading the datsheet got me even more confused.
Any ideas about this or any better/simpler?
