The MC3456 dual timing circuit is a highly stable controller capable
of producing accurate time delays, or oscillation. Additional terminals
are provided for triggering or resetting if desired. In the time delay
mode of operation, the time is precisely controlled by one external
resistor and capacitor per timer. For astable operation as an oscillator,
the free running frequency and the duty cycle are both accurately
controlled with two external resistors and one capacitor per timer. The
circuit may be triggered and reset on falling waveforms, and the output
structure can source or sink up to 200 mA or drive MTTL circuits.
