Functional Features

SN74LS153DR is a dual 4-line to 1-line data selector/multiplexer IC. It features active-low enable inputs (E1 and E2) that control the selection of one of the four input data lines (A0, A1, B0, B1) to be routed to the output line (Y). The selection is based on the logic levels applied to the enable inputs.

Advantages and Disadvantages

Advantages

• Low-power consumption due to Schottky technology
• Wide operating voltage range allows compatibility with various digital systems
• High-speed operation enables quick data selection and routing

Disadvantages

• Limited to 4-line data selection/multiplexing applications
• Active-low enable inputs may require additional circuitry for certain system designs

Working Principles

When both enable inputs (E1 and E2) are high (logic level 1), the outputs (C0 and C1) remain in a high-impedance state. When either enable input is low (logic level 0), the selected data inputs (A0, A1, B0, B1) are passed through to the corresponding outputs (C0, C1).

Detailed Application Field Plans

SN74LS153DR finds applications in various digital systems where data multiplexing and demultiplexing are required. Some specific application fields include: - Data communication systems - Digital signal processing - Microcontroller-based systems - Industrial automation - Robotics
