General Description
The LM555 is a highly stable device for generating accurate Y Adjustable duty cycle
time delays or oscillation Additional terminals are provided Y Output can source or sink 200 mA
for triggering or resetting if desired In the time delay mode Y Output and supply TTL compatible
of operation the time is precisely controlled by one external Y Temperature stability better than 0 005% per C
resistor and capacitor For astable operation as an oscil
