LM555 July 2006 Timer LM555TimerGeneral Description Features The LM555 is a highly stable device for generating accurate n Direct replacement for SE555/NE555 time delays or oscillation. Additional terminals are provided n Timing from microseconds through hours for triggering or resetting if desired. In the time delay mode of n Operates in both astable and monostable modes operation, the time is precisely controlled by one external n Adjustable duty cycle resistor and capacitor. For astable operation as an oscillator, n Output can source or sink 200 mA the free running frequency and duty cycle are accurately n Output and supply TTL compatible controlled with two external resistors and one capacitor. Thecircuit may be triggered and reset on falling waveforms, and n Temperature stability better than 0.005% per °C the output circuit can source or sink up to 200mA or drive n Normally on and normally off output TTL circuits. n Available in 8-pin MSOP package Applicationsn Precision timing n Pulse generation n Sequential timing n Time delay generation n Pulse width modulation n Pulse position modulation n Linear ramp generator Schematic Diagram 00785101 © 2006 National Semiconductor Corporation DS007851 www.national.com Connection Diagram LM555 Dual-In-Line, Small Outline and Molded Mini Small Outline Packages 00785103 Top View Ordering Information Package Part Number Package Marking Media Transport NSC Drawing 8-Pin SOIC LM555CM LM555CM Rails M08A LM555CMX LM555CM
