description/ordering information  
The ’HC148 devices feature priority decoding of  
the inputs to ensure that only the highest-order  
data line is encoded. These devices encode eight  
data lines to 3-line (4-2-1) binary (octal).  
Cascading circuitry (enable input EI and enable  
output EO) has been provided to allow octal  
expansion without the need for external circuitry.  
Data inputs and outputs are active at the low logic  
level.
