LM555

Single Timer

Features

Description

• High Current Drive Capability (200mA)

• Adjustable Duty Cycle

• Temperature Stability of 0.005%/C

• Timing From Sec to Hours

The LM555 is a highly stable controller capable of produc-

ing accurate timing pulses. With a monostable operation, the

time delay is controlled by one external resistor and one

capacitor. With an astable operation, the frequency and duty

cycle are accurately controlled by two external resistors and

one capacitor.

• Turn off Time Less Than 2Sec

Applications

8-DIP

• Precision Timing

• Pulse Generation

• Time Delay Generation

• Sequential Timing

8-SOIC
