Part Details:

LM555QML July 2006 LM555QML T Timer imer General Description n Adjustable duty cycle n Output can source or sink 200 mA The LM555 is a highly stable device for generating accurate n Output and supply TTL compatible time delays or oscillation. Additional terminals are providedfor triggering or resetting if desired. In the time delay mode of n Temperature stability better than 0.005% per °C operation, the time is precisely controlled by one external n Normally on and normally off output resistor and capacitor. For astable operation as an oscillator,the free running frequency and duty cycle are accurately Applications controlled with two external resistors and one capacitor. The n Precision timing circuit may be triggered and reset on falling waveforms, and n Pulse generation the output circuit can source or sink up to 200mA or drive n Sequential timing TTL circuits. n Time delay generation Features n Pulse width modulation n Pulse position modulation n Direct replacement for SE555/NE555 n Linear ramp generator n Timing from microseconds through hours n Operates in both astable and monostable modes Ordering Information NS Part Number SMD Part Number NS Package Number Package Description LM555H/883 H08A 8LD Metal Can LM555J/883 J08A 8LD Ceramic Dip Connection Diagrams Dual-In-Line Package Metal Can Package 20149833 Top View 20149803 Top View © 2006 National Semiconductor Corporation DS201498 www.national.com Schematic Diagram
