555 timer triggering
Thanks for the replys. I am using the monostable configuration that is shown in the datasheet (unsure of manufacture but I think its a universal configuration), it uses two external caps between pin 5 and 6 and a resistor between pin 7 and 8. A falling edge is supposed to trigger a high output from the 555 timer b... 27 May 2010 09:16

Im trying to tigger a 555 timer with a comparator. Im using the 555 timer in a monostable configuration with the supply voltage at 7 volts. When the input to the 555 comes via the high output of the comparator at 7 volts, the output of the 555 timer is high instead of low. But when the input to the 555 comes via th... 29 May 2010 10:17
