1 Features 3 Description •
•
•
• These devices are precision timing circuits capable of
producing accurate time delays or oscillation. In the
time-delay or mono-stable mode of operation, the
timed interval is controlled by a single external
resistor and capacitor network. In the a-stable mode
of operation, the frequency and duty cycle can be
controlled independently with two external resistors
and a single external capacitor. 1 • Timing From Microseconds to Hours
Astable or Monostable Operation
Adjustable Duty Cycle
TTL-Compatible Output Can Sink or Source
Up to 200 mA
