The 74153 IC Dual 4-Line to 1-Line Data Selector/Multiplexer DIP-16 is a versatile digital logic device that contains two independent 4-input multiplexers sharing common select and enable inputs. Each multiplexer can route one of four binary inputs to a single output based on the select logic levels. This IC enables efficient data routing, signal selection, and parallel-to-serial data conversion in digital systems. It offers high-speed performance, TTL compatibility, and low power consumption, making it ideal for applications in data processing, digital control, and communication circuits.
Features
- Dual 4-input multiplexers in a single IC package.
- Common select and enable inputs for both sections.
- High-speed TTL compatible logic operation.
- Low power consumption and reliable switching performance.
- Can perform data routing, logic function generation, and signal multiplexing.
- Wide operating voltage range and temperature stability.
- Standard 16-pin Dual In-Line Package (DIP-16) for easy prototyping.
- Suitable for both combinational logic and digital control circuits.
