DESCRIPTION

The 555 monolithic timing circuit is a highly stable controller capable of producing accurate time delays, or oscillation. In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor. For a stable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled with two external resistors and one capacitor. The circuit may be triggered and reset on falling waveforms, and the output structure can source or sink up to 200mA.

FEATURES

Turn-off time less than 2μs

Max. operating frequency greater than 500kHz

Timing from microseconds to hours

Operates in both astable and monostable modes

High output current

Adjustable duty cycle

TTL compatible

Temperature stability of 0.005% per °C

NOTES:

1.The junction temperature must be kept below 125°C for the D package and below 150°C for the FE, N and F packages. At ambient temperatures above 25°C, where this limit would be derated by the following factors:
