DESCRIPTION

The 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.

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
