Description
The KA555 is a highly stable controller capable of
producing accurate timing pulses. With monos table
operation, the time delay is controlled by one external
resistor and one capacitor. With astable operation, the
frequency and duty cycle are accurately controlled with two
external resistors and one capacitor.
