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 #9 7.62 0.300 2.54 0.100 1.50 ±0.10 0.059 ±0.004 #8 0.46 ±0.10 0.018 ±0.004 #16 19.80 MAX 0.780 #1 19.40 ±0.20 0.764 ±0.008 ( 0.81 ) 0.032 6.40 ±0.20 0.252 ±0.008 3.25 ±0.20 0.128 ±0.008 5.08 MAX 0.200 0.38 MIN 0.014 3.30 ±0.30 0.130 ±0.012 +0.10 0~15° 0.25 –0.05 +0.004 0.010 –0.002 3 KA558/KA558B Mechanical Dimensions (Continued) Package Dimensions in millimeters 16-SOP 0.05 0.002 0.51 ) 0.020 MIN #9 0.70 ±0.20 0.0275 ±0.008 4 1.27 0.050 1.80 MAX 0.071 8° MAX0.10 MAX0.004 3.95 ±0.20 0.156 ±0.008 0~ +0.10 0.20 -0.05 +0.004 0.008 -0.002 6.00 ±0.30 0.236 ±0.012 5.72 0.225 +0.10 0.406 -0.05 +0.004 0.016 -0.002 #8 9.90 ±0.20 0.39 ±0.008 #16 10.30 MAX 0.405 #1 ( 1.55 ±0.10 0.061 ±0.004 KA558/KA558B Ordering Information Product Number Package KA558B 16-DIP KA558BD KA558D2 16-SOP Operating Temperature 0 ~ + 70°C 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.
