Timers  
The MC1455 monolithic 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, time is precisely controlled by one external resistor and  
capacitor. 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. 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.
