Description

The SA555DX is a programmable timer and oscillator component in the electronic industry. It is a highly stable controller that can be used to produce accurate time delays or oscillation. In time delay mode, the timing is controlled by an external resistor and capacitor. In oscillator mode, the frequency and duty cycle are controlled with two external resistors and one capacitor. The SA555DX can be triggered and reset on falling waveforms and has a maximum output current of 200mA.
