NE555
Description
These devices are monolithic timing circuits capable of producing accurate time delays or oscillation.
Inthe time delay mode of operation, the timed interval is controll ed by a single external resistor and capacit
or netw ork. In the astable mode of operation, the frequency and duty cy cle may be independently
controlled wi th two external resistors and a si ngle external capacitor.
Features
• Timing from Microseconds to Hours
• Astable or Monostable Operation
• Adjustable Duty Cycle
• TTL - Compatible Output Can Sink or Source Up to 200 mA
• Temperature Stability of 0.005% per oC
• Direct Replacement for Signetics NE555 Timer
Applications
• Precision timing
• Pulse generation
• Sequential timing
• Time delay generation
• Pulse w idth modulation
• Pulse position modulation
• Missing pulse detector
