Overview
MC3456 Dual Timing Circuit 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.
