MC14538B  
Dual Precision  
Retriggerable/Resettable  
Monostable Multivibrator  
The MC14538B is a dual, retriggerable, resettable monostable  
multivibrator. It may be triggered from either edge of an input pulse,  
and produces an accurate output pulse over a wide range of widths, the  
duration and accuracy of which are determined by the external timing  
components, C and R . Output Pulse Width T = R @ C (secs)

Maximum ratings are those values beyond which device damage can occur.  
Maximum ratings applied to the device are individual stress limit values (not  
normal operating conditions) and are not valid simultaneously. If these limits are  
exceeded, device functional operation is not implied, damage may occur and  
reliability may be affected.

This device contains protection circuitry to guard against damage due to high  
static voltages or electric fields. However, precautions must be taken to avoid  
applications of any voltage higher than maximum rated voltages to this  
high−impedance circuit. For proper operation, V and V should be constrained
