74LS147 DIP IC

The 74LS147 IC is a 10-to-4 line priority encoder designed using TTL (Transistor-Transistor Logic) technology. It accepts 10 active-low input signals (0–9) and encodes them into a 4-bit binary code representing the highest-priority active input. The IC is housed in a standard DIP-16 (Dual Inline Package), making it ideal for breadboard and PCB applications in both educational and industrial projects.

One of the key features of the 74LS147 is its priority encoding capability, which ensures that when multiple inputs are active at once, the output represents only the highest-priority active input. This behavior is especially useful in applications like keypad encoding, interrupt management, and signal routing where input prioritization is required.

Features:

• Encodes 10 active-low inputs to a 4-bit binary output

• Priority encoding – outputs represent the highest-numbered active input

• TTL compatible for seamless integration with logic families

• Compact and reliable DIP-16 package

• Fast switching speeds with low power dissipation

Advantages:

• Reduces multiple input lines into fewer output lines

• Simplifies logic design in input-heavy applications

• Priority resolution prevents signal conflict

• Compatible with microcontrollers and digital systems

• Widely used in both learning and commercial environments

Applications:

• Keypad and keyboard encoding

• Interrupt controller systems

• Signal multiplexing and management

• Digital decision-making and control logic

• Data acquisition systems
