74HC155

The 74HC155 is a high-speed CMOS dual 1-of-4 line decoder/demultiplexer engineered for precision digital logic applications. It translates binary inputs into one of four outputs with minimal propagation delay and low power consumption, making it suitable for a wide range of modern digital circuit designs.

• Operates across a 2V to 6V supply range for compatibility with various digital systems.
• Propagation delay time of approximately 10 nanoseconds for rapid signal processing.
• Dual-channel architecture enables simultaneous decoding of two separate input sets.
• Low standby current consumption improves energy efficiency in battery-powered or low-power designs.
• Active low enable inputs provide flexible control over output activation.

Compared with older logic families, the 74HC155 offers faster switching speeds and reduced power usage while maintaining robust voltage tolerance and dual-decoder capability. Built on advanced CMOS technology, it delivers enhanced noise immunity and stable operation in electrically noisy environments. The device balances speed and power efficiency without compromising output accuracy and supports complex multiplexing and decoding tasks with reliable performance.
