Quad Timer
Features
Description

•
•
The KA558/KA558B 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.
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

Note :
1. The trigger functions only on the falling edge of the trigger pulse only after previously being high. After reset the trigger must
be brought high and then low to implement triggering.
2. For reset below 0.8V, outputs set low and trigger inhibited.
3. Output structure is open collector which requires a pull up resistor to VCC to sink current.
The output is normally low sinking current.
