LM555

Single Timer

Features

• High-Current Drive Capability: 200 mA

• Adjustable Duty Cycle

• Temperature Stability of 0.005%/°C

• Timing From μs to Hours

• Turn off Time Less Than 2 μs

Applications

• Precision Timing

• Pulse Generation

• Delay Generation

• Sequential Timing

Description

The LM555 is a highly stable controller capable of pro-

ducing accurate timing pulses. With a monostable opera-

tion, the delay is controlled by one external resistor and

one capacitor. With astable operation, the frequency and

duty cycle are accurately controlled by two external

resistors and one capacitor.
