Product Summary

The NE555 is a Precision Timer. The NE555 is a precision timing circuit capable of producing accurate time delays or oscillation. In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. The output circuit is capable of sinking or sourcing current up to 200 mA. Operation of the NE555 is specified for supplies of 5 V to 15 V. With a 5-V supply, output levels are compatible with TTL inputs.

Parametrics

NE555 absolute maximum ratings: (1)Supply voltage:18V; (2)Input voltage:18V; (3)Output current:±225mA; (4)Package thermal impedance:97℃/W; (5)Operating virtual junction temperature:150℃; (6)Storage temperature range:-65℃ to +150℃.

Features

NE555 features: (1)Timing From Microseconds to Hours; (2)Adjustable Duty Cycle; (3)Astable or Monostable Operation; (4)TTL-Compatible Output Can Sink or Source up to 200 mA.
