555 pulse timer circuit diagram basic

Posted on Feb 6, 2014

This causes T1 to conduct, taking pin 2 of IC1 `low`. IC1 then enters a timing cycle, the duration of which is et by R1/C1, causing pin 3 of IC1 to go`high`. This causes T2 to conduct. At the end of the timing cycle T2 switches off, and the circuit waits for the next pulse toT1. T1 replacements: ECG123AP or NTE123AP (Rotate device 180 ° to conform w
