LM555/NE555/SA555

Single Timer

Features

Description

• High Current Drive Capability (200mA)

• Adjustable Duty Cycle

• Temperature Stability of 0.005%/°C

• Timing From µSec to Hours

The LM555/NE555/SA555 is a highly stable controller

capable of producing accurate timing pulses. With a

monostable operation, the time delay is controlled by one

external resistor and one capacitor. With an astable

• Turn off Time Less Than 2µSec

operation, the frequency and duty cycle are accurately

controlled by two external resistors and one capacitor.

Applications

8-DIP

• Precision Timing

• Pulse Generation

• Time Delay Generation

• Sequential Timing
