Overview
KA555I is listed in the IC category. Available datasheets include documents from Fairchild Semiconductor.
Summary
Single Timer
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.
