Description
These devices are monolithic timing circuits capable of producing accurate time delays or oscillation. Inthe time delaymode of operation, the timed interval is controlled by a single external resistor and capacit or network. 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 width modulation
*Pulse position modulation
*Missing pulse detector
