Highest Priority: The encoder identifies the highest-priority active input and provides a binary output corresponding to that input.
Input Lines:
10 Binary Inputs: Accepts 10 lines of binary input (A0 to A9) representing the priority levels.
Binary Output:
4-Line Output: Generates a 4-line binary output (Y0 to Y3) based on the highest-priority active input.
Active-Low Outputs:
Active-Low: The outputs are active-low, meaning they are inverted.
Cascade Capability:
Cascade Connection: Multiple 74LS147s can be cascaded to encode more than 10 inputs.
Parallel Data Inputs:
Parallel Inputs: Allows parallel data input for efficient encoding.
Data Multiplexing: Employed in applications where multiple data sources need to be prioritized and encoded.
Automated Systems: Used in control systems where priority decisions are required.
