MC14541B  
Programmable Timer  
The MC14541B programmable timer consists of a 16stage binary  
counter, an integrated oscillator for use with an external capacitor and  
two resistors, an automatic poweron reset circuit, and output control  
logic.  
Timing is initialized by turning on power, whereupon the poweron

reset is enabled and initializes the counter, within the specified V  
DD  
range. With the power already on, an external reset pulse can be  
applied. Upon release of the initial reset command, the oscillator will
