NXP Semiconductors 74F148
The 74F148 8-input priority encoder accepts data from eight active-Low inputs and provides a binary representation on the three active-Low outputs. The GS is active-Low when any input is Low: this indicates when any input is active.| Part No. | 74F148 |

FEATURES
● Code conversions● Multi-channel D/A converter
● Decimal-to-BCD converter
● Cascading for priority encoding of “N” bits
● Input enable capability
● Priority encoding-automatic selection of highest priority input line
● Output enable-active Low when all inputs are High
● Group signal output-active when any input is Low
DESCRIPTION
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 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.
