ON Semiconductor MC74HC251ADTR2G Product Overview

The MC74HC251ADTR2G from ON Semiconductor is a high-performance integrated circuit that forms part of the 74HC (High-Speed CMOS) family. This particular device is a 3-state non-inverting multiplexer which is designed to select one of the eight data inputs to a single output, based on the conditions of three selection inputs. It is widely used in digital systems where high speed, low power consumption, and efficient data routing are required.

The device features an 8-input multiplexer with three binary control inputs (A, B, and C) and an enable input (E). The eight inputs are designated as I0 through I7, and the output is labeled as Y. When the enable input (E) is high, the Y output is in a high impedance state, effectively disconnecting it from the circuit, which allows for multiple devices to be connected to a common bus without interference.

The MC74HC251ADTR2G operates over a wide voltage range from 2V to 6V and offers a balanced propagation delay and transition times, which makes it suitable for use in a variety of applications that require fast switching performance. The low quiescent current ensures that the device consumes minimal power when not actively switching, contributing to energy-efficient designs.

This multiplexer is available in a TSSOP-16 (Thin Shrink Small Outline Package) which provides a compact footprint while still offering excellent thermal performance and easy integration into a wide range of electronic systems. The device is also characterized for operation from -55°C to 125°C, making it suitable for extreme environmental conditions.

Common applications for the MC74HC251ADTR2G include data routing in communication systems, signal multiplexing in audio/video equipment, control signal routing in automation and industrial systems, and as a function generator in test equipment. Its robust design and flexibility make it an ideal choice for designers seeking a reliable multiplexer for their digital circuits.

ON Semiconductor's commitment to quality ensures that the MC74HC251ADTR2G meets stringent industry standards for performance and reliability, making it a trusted component for engineers and manufacturers around the globe.
