| www.fairchildsemi.com KA558/KA558B Quad Timer 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 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.

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. 2 KA558/KA558B Mechanical Dimensions Package Dimensions in millimeters 16-DIP 0.81 ) 0.032 #16 6.40 0.20 0.252 0.008 #1 ( 19.80 MAX 0.780 19.40 0.20 0.764 0.008 #8 #9 7.62 0.300 3.25 0.20 0.128 0.008 0.38 MIN 0.014 5.08 MAX 0.200 3.30 0.30 0.130 0.012 0~15 0.25 -0.05 0.010 -0.002 +0.004 +0.10 2.54 0.100 0.46 0.10 0.018 0.004 1.50 0.10 0.059 0.004 3 KA558/KA558B Mechanical Dimensions (Continued) Package Dimensions in millimeters 16-SOP MIN 1.55 0.10 0.061 0.004 #1 #16 10.30 MAX 0.405 9.90 0.20 0.39 0.008 #8 #9 6.00 0.30 0.236 0.012 3.95 0.20 0.156 0.008 1.80 MAX 0.071 +0.10 0.20 -0.05 +0.004 0.008 -0.002 5.72 0.225 0.70 0.20 0.0275 0.008 4 0~ 8 MAX0.10 MAX0.004 1.27 0.050 +0.10 0.406 -0.05 +0.004 0.016 -0.002 ( 0.51 ) 0.020 0.05 0.002 KA558/KA558B Ordering Information Product Number KA558B KA558BD KA558D2 Package 16-DIP 16-SOP 0 ~ + 70C Operating Temperature 5 KA558/KA558B DISCLAIMER FAIRCHILD SEMICONDUCTOR RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE RELIABILITY, FUNCTION OR DESIGN.
