Preliminary Ii TDA0555,D II TIMER TheTDA0555D is a monolithic timer, equivalent to the NE555, however it is mounted in a miniature plastic package. It is a highly stable controller capable of producing accurate time delays or oscillations. In the time delay mode of operation the timer is controlled by one external resistor and capacitor. For operation as an oscillator the frequency and the duty factor are both accurately controlled by two external resistors and one capacitor. Additional terminals are provided for triggering or resetting. The circuit maybe triggered and reset on the falling-edge ~f a waveform.
