Diodes - 555 Timer ICs

Drop-in Replacements for Industry Standard ICs

Continuing the expansion of its standard linear product portfolio, Diodes Incorporated has announced the introduction of a series of low-cost 555 timer ICs. 

Originally developed more than forty years ago, the 555 was the first commercially available timer, providing designers with an inexpensive, stable and user-friendly circuit.  The 555 timers are broadly used in a wide variety of applications ranging from electronic toys to industrial controls.  With hundreds of millions of units estimated to be manufactured each year, the 555 continues to have widespread use and today remains a first choice in a multitude of precision timer, oscillator and pulse-generation applications.

The NE555, SA555 and NA555 devices are precision timing circuits 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.
In the astable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor.
The three devices offer a selection of operating temperature ranges:

  • NE555 0 to 70ºC
  • SA555 -40 to 85ºC
  • NA555 -40 to 105ºC

All three devices are supplied in a small outline 8 pin package (SO-8).
The Diodes’ Advantage:

  • Industry standard part number and specification
    Economic drop in replacement for alternative parts
  • Simple programming
    Mode of operation simply set by the addition of one (monostable mode) or two (astable mode) resistors and a capacitor.
  • Three operating temperature ranges
    Compatibility commercial and industrial system requirements.
  • Wide operating voltage
    Operation specified from 4.5V to 16V. 5V supply provides output compatibility with TTL levels.
