SEMICONDUCTOR TECHNICAL DATA  
High–Performance Silicon–Gate CMOS  
The MC74HC147 is identical in pinout to the LS147. The device inputs are  
compatible with standard CMOS outputs; with pullup resistors, they are  
compatible with LSTTL outputs.  
N SUFFIX  
PLASTIC PACKAGE  
CASE 648–08  
16  
This device encodes nine active–low data inputs to four active–low BCD  
Address Outputs, ensuring that only the highest order active data line is  
encoded. The implied decimal zero condition is encoded when all nine data  
inputs are at a high level (inactive).
