Functional Features

The SN74HC258N is a multiplexer/demultiplexer IC that allows the selection of one out of four input lines to be routed to a single output line. It operates at high speed and utilizes CMOS logic, ensuring low power consumption. The 3-state outputs provide flexibility in connecting multiple devices.

Advantages and Disadvantages

Advantages: - High-speed operation - Low power consumption - Versatile 3-state outputs - Wide supply voltage range

Disadvantages: - Limited number of inputs and outputs - Not suitable for high-frequency applications

Working Principles

The SN74HC258N operates based on the principle of multiplexing and demultiplexing. When the control input (C) is low, the IC functions as a multiplexer, selecting one of the four input lines (A0-A3 or B0-B3) based on the binary value applied to the address inputs (A0-A2). The selected input is then routed to the output (Y).

When the control input (C) is high, the IC functions as a demultiplexer, routing the input (B0-B3) to one of the four output lines (Y) based on the binary value applied to the address inputs (A0-A2).

Detailed Application Field Plans

The SN74HC258N finds applications in various fields, including:

  1. Data communication systems
  2. Digital multiplexing/demultiplexing circuits
  3. Address decoding in microprocessors
  4. Signal routing in electronic test equipment
  5. Industrial automation and control systems
