period determined by the external resistor Rx and  
capacitor Cx. When Cx > 10nF and Rx > 10KΩ,  
the output pulse width value is approsimatively

(K 0.45).  
DESCRIPTION  
The M74HC123 is an high speed CMOS  
MONOSTABLE MULTIVIBRATOR fabricated with  
silicon gate C MOS technology.  
Taking CLR low breaks this MONOSTABLE  
STATE. If the next trigger pulse occurs during the  
2
MONOSTABLE  
period  
it  
makes  
the  
MONOSTABLE period longer. Limit for values of  
Cx and Rx : Cx : NO LIMIT  
There are two trigger inputs, A INPUT (negative  
edge) and B INPUT (positive edge). These inputs  
are valid for slow rising/falling signals, (tr=tf=l sec).  
The device may also be triggered by using the  
CLR input (positive-edge) because of the  
Schmitt-trigger input; after triggering the output  
maintains the MONOSTABLE state for the time

All inputs are equipped with protection circuits
