original creation date: 08/02/95 last update date: 02/17/97 last major revision date: 08/02/95 mnlm555-x rev 0b0 microcircuit data sheet precision timer general description the lm555 is a highly stable device for generating accurate time delays or oscillation. additional terminals are provided for triggering or resetting if desired. in the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor. for astable operation as an oscillator, the free running frequency and duty cycle are accurately controlled with two external resistors and one capacitor. the circuit may be triggered and reset on falling waveforms, and the output circuit can source or sink up to 200ma or drive ttl circuits. ns part numbers lm555h/883 lm555j/883 industry part number lm555 prime die lm555 processing mil-std-883, method 5004 quality conformance inspection mil-std-883, method 5005 subgrp description temp ( c) o 1 static tests at +25 2 static tests at +125 3 static tests at -55 4 dynamic tests at +25 5 dynamic tests at +125 6 dynamic tests at -55 7 functional tests at +25 8a functional tests at +125 8b functional tests at -55 9 switching tests at +25 10 switching tests at +125 11 switching tests at -55 1
