74F148 8-input Priority EncoderThe 74F148 8-input priority encoder accepts data from eight
active-Low inputs and provides a binary representation on the three
active-Low outputs. A priority is assigned to each input so that when
two or more inputs are simultaneously active, the input with the
highest priority is represented on the output, with input line I7 having
the highest priority. A High on the Enable Input (EI) will force all
outputs to the inactive (High) state and allow new data to settle
without producing erroneous information at the outputs. A Group
Signal (GS) output and an Enable Output (EO) are provided with the
three data outputs. The GS is active-Low when any input is Low:
this indicates when any input is active. The EO is active-Low when
all inputs are High. Using the Enable Output along with the Enable
Input allows priority encoding of N input signals. Both EO and GS
are active-High when the Enable Input is High.
