LM555I

LM555/I SINGLE TIMER SINGLE TIMER The LM555/I is a highly stable controller capable of producing accurate timing pulses. With monostable operation, the time delay is controlled by one external and one capacitor. With astable operation, the frequency and duty cycle are accurately controlled with two external resistors and one capacitor. 8 DIP FEATURES High Current Drive Capability (= 200mA) Adjustable Duty Cycle Temperature Stability of 0.005%/°C Timing From µSec To Hours Turn Off Time Less Than 2µSec 8 SOP APPLICATIONS Precision Timing Pulse Generation Time Delay Generation Sequential Timing ORDERING INFORMATION BLOCK DIAGRAM Device Package LM555CN 8 DIP LM555CM 8 SOP LM555CIN 8 DIP LM555CIM 8 SOP Operating Temperature 0 ~ +70°C -40 ~ +85°C ©1999 Fairchild Semiconductor Corporation Rev.
