Description
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.
