KA558B

四定时器 Quad Timer

Description

The KA558/ series are monolithic Quad Timers which can be used to produce four entirely independent timing functions. 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 controlled 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
