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

Note 1: This parameter influences the maximum value of the timing resistors RA and RB in the circuit on Fig 1. For example, when
VCC=5V, the maximum value is R=RA+RB=3.4 M, and VCC=15V, the maximum value is 10 M.
Note 2: For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions.
Note 3: Timing interval error is defined as the difference between the measured value and the average value of a random sample from
each process run.
Note 4: Values specified are for a device in a monostable circuit similar to Fig. 2, with component values as follow: RA=2Kto 100 K,
C=0.1µF.
Note 5: Values specified are for a device in an astable circuit similar to Fig. 1, with component values as follow: RA, RB=1Kto 100 K,
C=0.1µF.
