Product Overview: CD74HC251E Logic Multiplexer from Texas Instruments

The CD74HC251E is a high-speed CMOS logic 8-input multiplexer with three-state outputs from Texas Instruments, designed to be used in applications requiring a high degree of precision and speed. This integrated circuit (IC) is part of the 74HC family, which is well-known for its high noise immunity and low power consumption compared to other logic families.

The multiplexer features eight input channels, a common output enable, and a single three-state output that can present either a high, low, or high-impedance state. The three-state output allows multiple outputs to be connected together for bus-oriented applications, providing a versatile solution for complex digital systems. The CD74HC251E operates on a wide voltage range from 2V to 6V, making it compatible with a variety of digital systems.

With its low power dissipation and balanced propagation delays, the CD74HC251E is optimized for use in high-frequency data paths and control environments. The IC's pin configuration is designed for simplified PCB layout, and its standard DIP (Dual In-line Package) makes it suitable for breadboard prototyping as well as for permanent soldered applications in commercial and industrial devices.
