Functional Features

• CD74ACT253M96 is a dual 4-input multiplexer with common select inputs (S) and complementary outputs (Y and Y̅).
• It can be used as a multiplexer or demultiplexer depending on the logic level applied to the select input.
• The device operates at high speed while consuming low power, making it suitable for various digital applications.
• It has a wide supply voltage range, allowing flexibility in different electronic systems.

Advantages and Disadvantages

Advantages

• High-speed operation enables efficient data routing.
• Low power consumption helps in reducing overall energy usage.
• Wide supply voltage range provides compatibility with different systems.
• Compact 16-pin SOIC package allows for easy integration into circuit boards.

Disadvantages

• Limited number of inputs and outputs may restrict its use in complex systems requiring more connections.
• Propagation delay of 5.5 ns may introduce slight timing issues in certain applications.

Working Principles

The CD74ACT253M96 functions as a multiplexer or demultiplexer based on the logic level applied to the select input (S). When S is low, the device operates as a multiplexer, where one of the four data inputs (A0-A3) is selected and routed to the output (Y). Conversely, when S is high, the device acts as a demultiplexer, with the selected input (B0-B3) being transmitted to the output (Y).

Detailed Application Field Plans

CD74ACT253M96 finds applications in various digital systems, including:

1. Data communication networks
2. Multiplexing audio/video signals
3. Address decoding in microcontrollers
4. Data routing in computer architectures
5. Signal selection in test and measurement equipment
