The SN74HC148N is an integrated circuit (IC) component that belongs to the 74HC family of high-speed CMOS logic devices. This IC is specifically designed as a priority encoder, which means it can encode the highest priority active input into a binary code output.
Key Features:
1. Priority Encoder: The SN74HC148N is equipped with eight data input lines (D0 to D7), and three outputs (Y0 to Y2). The inputs are prioritized, and the highest priority input that is active (set low) is encoded onto the outputs in a binary format.
2. Eight Active-Low Inputs: The IC has eight input pins (D0 to D7) that accept binary data inputs. These inputs are active-low, meaning that a low logic level represents an active input and is prioritized for encoding.
3. Three Binary Outputs: The three outputs (Y0 to Y2) are used to represent the binary code of the highest priority active input. The output pins are active-low, providing a low logic level when corresponding input is active.
4. Cascadable: Multiple SN74HC148N ICs can be cascaded together to encode a larger number of inputs. By connecting the cascaded inputs (D0 to D7) of one IC to the outputs (Y0 to Y2) of another IC, a higher number of inputs can be encoded
