  15. Vcc: Positive Power Supply
  16. Y: Multiplexed Output

Functional Features

The SN74159N is designed to perform data selection and multiplexing functions. It features the following:

  • 4-bit address inputs (A0-A3) to select one of the 16 data inputs (B, C, D, F, H, I, J, K)
  • Enable input (E) to enable/disable the multiplexer
  • Multiplexed output (Y) that carries the selected data input

Advantages and Disadvantages

Advantages: - High-speed operation - Low-power consumption - Wide operating temperature range - Compact DIP package for easy integration

Disadvantages: - Limited number of data inputs (8 in total) - Requires external components for more complex multiplexing operations

Working Principles

The SN74159N works by using the address inputs to select one of the data inputs. When the enable input is active, the selected data input is passed through to the multiplexed output. The propagation delay time determines the time it takes for the output to respond to a change in the address or data inputs.

Detailed Application Field Plans

The SN74159N can be used in various applications, including:

  1. Data routing and selection in digital systems
  2. Address decoding in memory systems
  3. Input/output expansion in microcontrollers
  4. Multiplexing of analog signals in communication systems
