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.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-
ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-
tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. Values are at TA = 25°C unless otherwise noted.
