The 74HC258D,653 has a total of 16 pins. The pin configuration is as follows:
The 74HC258D,653 is a quad 2-input multiplexer with common select inputs (E) and an active-low enable input. It features high-speed operation and low power consumption, making it suitable for various applications.
The device can be used as a multiplexer, where one of the four data inputs can be selected and routed to the output line based on the address inputs (A, B, C, D) and the enable input (E). It can also function as a demultiplexer, where the data from the input line is routed to one of the four output lines based on the address inputs and the enable input.
Advantages: - High-speed operation allows for quick data selection and routing. - Low power consumption helps in reducing overall system power requirements. - Compact SOIC package enables space-efficient designs. - Wide supply voltage range provides flexibility in different applications.
Disadvantages: - Limited number of data inputs and output lines restricts the complexity of multiplexing/demultiplexing operations. - Propagation delay may introduce timing issues in certain high-frequency applications.
The 74HC258D,653 operates based on the principles of digital logic. The enable input (E) controls the selection of data inputs, while the address inputs (A, B, C, D) determine which input is routed to the output line. When the enable input is active (low), the selected data input is passed through to the output line. When the enable input is inactive (high), the output remains in a high-impedance state.
The 74HC258D,653 finds applications in various fields, including:
There are several alternative models available that offer similar functionality to the 74HC258D,653. Some of the notable alternatives include:
