MC14532B  
8−Bit Priority Encoder  
The MC14532B is constructed with complementary MOS (CMOS)  
enhancement mode devices. The primary function of a priority  
encoder is to provide a binary address for the active input with the  
highest priority. Eight data inputs (D0 thru D7) and an enable input  
(E are provided. Five outputs are available, three are address outputs

Stresses exceeding Maximum Ratings may damage the device. Maximum  
Ratings are stress ratings only. Functional operation above the Recommended  
Operating Conditions is not implied. Extended exposure to stresses above the  
Recommended Operating Conditions may affect device reliability.

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
