555 timer

hello, this may seem like a dumb question but what do you do to reset a
555 timer on pin 4? 5V, a pulse, etc ?


Thanks

 

Is it also not true that it must be pulled high (or allowed to go high) at
the end of the reset interval, before the timing cycle will start?

http://www.national.com/ds/LM/LMC555.pdf - this is the CMOS version;
does anyone use bipolar 555s any more?

Thanks,
Rich

For the device the OP asked about, the 555, releasing the low on the
RESET- input will be sufficient to enable the chip. Whether the
chip will start a timing cycle at that time depends on some other
factors.
