CD74HC153EG4

The CD74HC153EG4 is a dual 4-to-1 multiplexer integrated circuit (IC) manufactured by Texas Instruments. It belongs to the 74HC (High-Speed CMOS) family, which is known for its high-speed operation and low power consumption. Here’s a detailed description of its features and specifications:

General Features:

• Functionality: The CD74HC153 is designed to select one of four data inputs (D0 to D3) for each of its two channels (A and B) based on the values of two select lines (S0 and S1). This allows for efficient data routing in digital circuits.
• Dual Multiplexer: The device contains two independent 4-to-1 multiplexers, enabling it to handle two separate data streams simultaneously.
• High-Speed Operation: The HC series is optimized for high-speed performance, making it suitable for applications requiring fast data processing.
• Low Power Consumption: The CMOS technology used in this IC ensures low static and dynamic power consumption, making it ideal for battery-operated devices.

Pin Configuration:

• The CD74HC153EG4 typically comes in a 16-pin dual in-line package (DIP) or surface-mount package (SOIC), with each pin serving a specific function:
  • Inputs: Four data inputs (D0, D1, D2, D3) for each multiplexer.
  • Select Lines: Two select lines (S0, S1) that determine which data input is routed to the output.
  • Outputs: Two outputs (Y0, Y1) corresponding to each multiplexer.
  • Enable Pins: The device includes enable pins (G1, G2) that control the operation of the multiplexers.

Electrical Characteristics:

• Supply Voltage (Vcc): The IC operates typically at a supply voltage range of 2V to 6V, making it compatible with various logic levels.
• Input Voltage Levels: The input high voltage (VIH) and input low voltage (VIL) thresholds are defined to ensure reliable operation across different logic families.
• Propagation Delay: The propagation delay time is typically in the range of nanoseconds, allowing for rapid switching and data selection.

Applications:

• Data Routing: The CD74HC153 is commonly used in applications where data needs to be routed from multiple sources to a single destination, such as in communication systems and data acquisition systems.
• Signal Multiplexing: It is ideal for multiplexing signals in audio, video, and other electronic systems.
• Logic Functions: The device can be used in various logic functions and combinational logic circuits.

Package Information:

• The "EG4" suffix indicates that the part is lead-free and compliant with RoHS (Restriction of Hazardous Substances) standards, making it environmentally friendly.

Summary:

The CD74HC153EG4 from Texas Instruments is a versatile and efficient dual 4-to-1 multiplexer that offers high-speed performance and low power consumption. Its dual-channel capability and ease of integration make it a popular choice for a wide range of digital applications.
