Description
The NE558 series are monolithic Quad Timers which can be used to produce four entirely independent timing func tions. These highly stable, general purpose controllers can be used in a monostable mode to produce accurate time delays, from microseconds to hours. The time is precisely con trolled by one external resistor and one capacitor in the time delay mode. A stable mode can be operated using two of four time sections.

Features
• Wide Supply Voltage Range: 4.5V To 16V
• 100 mA Output Current Per Section
• Edge Triggered Without Coupling Capacitor
• Time Period Equals RC
• Output independent Of Trigger Conditions

Applications
• Quad One-Shot
• Sequential Timing
• Precision Timing
• Time Delay Generation
