Part Number	NE558D Datasheet
Manufacturer	Philips Semiconductors
Overview	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. * 100 mA output current per section * Edge-triggered (no coupling capacitor) * Output independent of trigger conditions * Wide supply voltage range 4.5 V to 16 V * Timer intervals from microseconds to hours * Time period equals RC * Military qualifications pending. APPLICATIONS * Sequential timing *.
