DESCRIPTION  
The HCC/HCF40147B CMOS encoder features  
priority encoding of the inputs to ensure that only the  
highest order data line is encoded. Ten data input  
lines (0-9) are encoded to four line (8, 4, 2, 1) BCD.  
The highest priority line is line 9. All four output lines  
are logic 1 (VSS) when all input lines are logic 0. All  
inputs and outputs are buffered, and each output  
can drive one TTL Low Power Schottky load. The  
HCC/HCFF40147 is functionally similar to the  
T54/T74LS147 if pin 15 is tied low.  
The HCC/HCF40147B types are supplied in 16lead  
plastic or ceramic and plastic micropackage.
