  Hey Nick, Nicholas Yunker said: 1) I would be interested to know, what is the maximum pulse width of a trigger pulse need to be to correctly trigger the TLC556 in mono-stable mode? I verified with Alex that our simulation works if we release the trigger…

  Part Number: TLC556 Hi, I actually used a TLC556 in a new design. Never thought I'd have the chance again. Go figure. :-) Because the TRIG input is edge-sensitive I used the one-shot output of the first-half of the dual-timer to generate an RC pul…
