description  
The ’HC148 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  
needforexternalcircuitry. Datainputsandoutputs  
are active at the low logic level.
