Functional Features

• The 74AHC157PW,118 is a quad 2-input multiplexer.
• It selects one of the four data inputs (A, B, C, or D) based on the select inputs (A1, A2, A3).
• The selected input is then routed to the output (Y).

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data selection. - Low power consumption helps in reducing energy usage.

Disadvantages: - Limited number of inputs and outputs restricts its application to smaller systems. - Propagation delay may affect real-time applications.

Working Principles

The 74AHC157PW,118 operates based on the principle of digital logic multiplexing. It uses select inputs (A1, A2, A3) to choose one of the four data inputs (A, B, C, D). The selected input is then passed through internal circuitry and routed to the output (Y).
