KA555 Datasheet | Fairchild Semiconductor

Features - High Current Drive Capability (200m A) - Adjustable Duty Cycle - Temperature Stability of 0.005%/°C - Timing From µsec to Hours - Turn Off Time Less Than 2µsec Applications - Precision Timing - Pulse Generation - Time Delay Generation - Sequential Timing .fairchildsemi. Description 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 p. 8 Vcc Discharging Tr. 7 Discharge Output 3 Out Put Stage F/F Reset 4 Vref p. 6 Threshold Control Voltage ©2002 Fairchild Semiconductor Corporation Rev. 1.0.3 Absolute Maximum Ratings (TA = 25°C) Parameter Supply Voltage Lead Temperature (Soldering 10sec) Power Dissipation Operating Temperature Range KA555/KA555I Storage Temperature Range Symbol Value...
