74HC153

The 74HC153 is a high-speed CMOS dual 4-line to 1-line multiplexer engineered for efficient, reliable data routing in digital circuits. It contains two independent 4-to-1 multiplexers with common select inputs, enabling flexible selection of signals while conserving board space and simplifying layout compared with separate single-channel devices. Key electrical and functional characteristics described for the 74HC153 include an operating voltage range of 2V to 6V for broad system compatibility, typical propagation delay around 11 ns to support fast switching, low quiescent current near 80 µA for energy-conscious designs, and TTL-compatible inputs to ease interfacing with standard logic families. Built with CMOS technology, the device balances low power consumption and signal integrity. Its dual-channel architecture makes it well suited to applications that require parallel data selection or compact multiplexing of multiple signals, such as data selectors, control signal routing, and timing-sensitive digital logic systems. The robust design helps minimize noise susceptibility while delivering the switching performance expected in modern digital implementations. Because the 74HC153 integrates two multiplexers with common select lines and compact pinning, it can reduce component count and routing complexity in multi-channel designs without sacrificing speed or compatibility.
