Product Description: 74LS154 DIP 4-Line to 16-Line Decoder/Demultiplexer

The 74LS154 is a 4-line to 16-line decoder/demultiplexer housed in a DIP-24 package. This integrated circuit (IC) is designed to decode 4 binary input bits into one of 16 output lines. It is commonly used in digital systems for address decoding, data routing, and signal multiplexing, where one of 16 different channels or devices needs to be selected based on a 4-bit binary input.

The 74LS154 features active-low outputs, meaning that one of the output lines will be pulled low based on the binary input, while the other 15 outputs remain high. It is a demultiplexer in the sense that it takes a single 4-bit input and routes it to one of 16 output lines. It also includes an enable pin to disable the entire IC, providing an easy way to turn off the decoder when not in use, saving power and reducing noise.

This IC is TTL-compatible, ensuring it is easily integrated into systems based on TTL logic and providing high-speed operation with low power consumption. The 74LS154 is often used in memory addressing, peripheral device control, signal routing, and data multiplexing, offering a flexible and efficient solution for digital circuits that require 16 output lines from a 4-bit address.

Features:

  • 4-Line to 16-Line Decoder/Demultiplexer: Decodes 4 binary input lines into 16 output lines, providing one-to-one mapping of the input to the output.
  • Active-Low Outputs: The output lines are active-low, meaning only one output will be low (active) at a time, corresponding to the 4-bit input, and the remaining 15 outputs will remain high.
  • Enable Pin: The enable pin can be used to disable the IC entirely, allowing the decoder to be turned off when not needed to save power.
  • TTL Compatible: Fully TTL-compatible with other TTL logic devices, making it easy to integrate into a wide range of digital systems.
  • High-Speed Operation: The IC is designed for high-speed operation, ensuring fast decoding and efficient signal routing.
  • Low Power Consumption: The 74LS154 operates with low power consumption, which is ideal for energy-efficient applications.
  • DIP-24 Package: The IC comes in a DIP-24 package, making it easy to mount on breadboards for prototyping or integrate into printed circuit boards (PCBs) for final product designs.

Applications:

  • Memory Address Decoding: The 74LS154 is commonly used in memory systems where a 4-bit address is required to select one of 16 memory locations or modules.
  • Peripheral Device Control: In digital systems, the IC can be used to select one of 16 peripherals or output channels based on a 4-bit control signal.
  • Data Routing: The 74LS154 is ideal for data routing in complex systems, where data needs to be directed to one of 16 output lines based on the input address.
  • Signal Multiplexing: The IC can be used in signal multiplexing applications, enabling the selection of one out of 16 possible signals for processing or transmission.
  • Control Systems: In control systems, the 74LS154 can be used to direct control signals to one of 16 different devices, subsystems, or parts of a larger system.
  • Timing and Sequencing: In timing circuits and sequencing systems, the decoder can be used to generate a specific timing signal or activate one of 16 stages in a sequence.
  • Digital Circuitry: The IC is useful for combinational logic applications, where one of 16 outputs needs to be activated based on a 4-bit input address, such as in digital counters or event detection systems.

Package Included:

  • 1 x 74LS154 4-Line to 16-Line Decoder/Demultiplexer IC
