INTEGRATED CIRCUITS NE558 Quad timer Product data Supersedes data of 2001 Aug 03 Philips Semiconductors 2003 Feb 14 Philips Semiconductors Quad timer Product data NE558 DESCRIPTION The NE558 Quad Timers are monolithic timing devices which can be used to produce four independent timing functions.
The NE558 output sinks current.
These highly stable, general purpose controllers can be used in a monostable mode to produce accurate time delays—from microseconds to hours.
In the time delay mode of operation, the time is precisely controlled by one external resistor and one capacitor.
A stable operation can be achieved by using two of the four timer sections.
The four timer sections in the NE5...
