74HC148 8 to 3-Line Priority Encoder SMD IC
The 74HC148 8-to-3-Line Priority Encoder SMD IC is a high-performance encoder designed to simplify and prioritize input data in digital circuits, particularly in systems requiring multiple signal inputs but limited output lines. This IC converts eight active-low inputs into a 3-bit binary output, where the highest-priority active input takes precedence. This functionality is especially valuable in applications where input lines need to be efficiently managed, such as interrupt handling in microcontrollers, address decoding, and other decision-making circuits. The 74HC148 takes in eight active-low inputs (I0 to I7) and generates a binary code corresponding to the highest-priority input. This IC not only provides a straightforward way to encode input signals but also helps reduce the number of wires needed in digital systems by consolidating several inputs into a smaller binary code. Priority is assigned in descending order, where input I7 has the highest priority and I0 the lowest. The IC outputs a 3-bit binary code corresponding to the highest active input line, effectively enabling selective processing in complex systems.
