KA555 Single Timer • High Current Drive Capability 200mA • Adjustable Duty Cycle • Temperature Stability of 0.005%/°C • Timing From µsec to Hours • Turn Off Time Less Than 2µsec • Precision Timing • Pulse Generation • Time Delay Generation • Sequential Timing The KA555 is a highly stable controller capable of producing accurate timing pulses. With a monostable operation, the time delay is controlled by one external resistor and one capacitor. With an astable operation, the frequency and duty cycle are accurately controlled by two external resistors and one capacitor. 8-DIP 1 8-SOP Internal Block Diagram GND 1 Trigger 2 Comp. 8 Vcc Discharging Tr. 7 Discharge Output 3 OutPut Stage Reset 4 Vref Comp. 6 Threshold Control Voltage 2002 Fairchild Semiconductor Corporation KA555 Absolute Maximum Ratings TA = 25°C Parameter Supply Voltage Lead Temperature Soldering 10sec Power Dissipation Operating Temperature Range KA555/KA555I Storage Temperature Range Value Unit TLEAD TOPR 0 ~ +70 / -40 ~ +85 TSTG -65 ~ +150 KA555 Electrical Characteristics TA = 25°C, VCC = 5 ~ 15V, unless otherwise specified Parameter Supply Voltage Supply Current Low Stable Note1 Timing Error MonoStable Initial Accuracy Note2 Drift with Temperature Note4 Drift with Supply Voltage Note4 Timing Error Astable Initial Accuracy Note2 Drift with Temperature Note4 Drift with Supply Voltage Note4 Control Voltage Symbol VCC ICC ACCUR Ordering Information Product Number KA555 KA555D KA555I KA555ID Package 8-DIP 8-SOP 8-DIP 8-SOP Operating Temperature 0 ~ +70°C -40 ~ +85°C KA555 KA555 DISCLAIMER FAIRCHILD SEMICONDUCTOR RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE RELIABILITY, FUNCTION OR DESIGN.
