The SN74HC148NSR is a 8-line to 3-line priority encoder integrated circuit (IC) component. It is commonly used in digital electronics and communication systems to prioritize multiple inputs and generate a binary output based on the highest priority input.
Key features of the SN74HC148NSR include:
1. High-Speed Operation: The IC component is designed to operate at high speed, allowing it to handle real-time inputs and generate the output quickly.
2. 8-Line Input: It has eight input pins (A0 - A7) to accept eight different input lines. These input lines can be in any combination of high and low logic levels.
3. 3-Line Output: The IC component has three output pins (Y0 - Y2) to provide a binary code based on the priority of the input lines. The output lines are active-low, meaning they generate a low logic level when they are selected.
4. Priority Encoding: The SN74HC148NSR uses priority encoding to determine the highest priority input line and generate the corresponding binary code on the output pins. The highest priority input line is assigned the lowest binary value (Y2), while the lowest priority input line is assigned the highest binary value (Y0).
5. Cascadable: This IC component can be cascaded with other similar devices to handle a larger number of input lines
