ON Semiconductor MC74ACT257NG Quad 2-Input Multiplexer

The MC74ACT257NG is a high-performance, quad 2-input multiplexer integrated circuit from ON Semiconductor, designed to provide efficient data selection to the desired output lines. This versatile component is a crucial element in various digital systems where signal routing is necessary, such as data processing, communication systems, and control applications.

Constructed with advanced CMOS technology, the MC74ACT257NG offers a perfect blend of speed and power consumption, making it an ideal choice for battery-operated and power-sensitive applications. The device operates over a broad voltage range of 4.5V to 5.5V, ensuring compatibility with TTL-level logic while maintaining CMOS-level power dissipation.

The multiplexer features four individual 2-input multiplexers with common select and enable inputs. Each multiplexer has two data inputs (A and B), one output (Y), a common select input (S), and an output enable input (OE). The select input determines which of the data inputs A or B is routed to the output Y. When the output enable (OE) is low, the selected input is passed through to the output; when OE is high, the output is in a high-impedance state, effectively isolating the multiplexer from the output line.

Key attributes of the MC74ACT257NG include:

• Fast switching speeds, which minimize transition delays and improve system performance.
• Low power consumption, which extends battery life and reduces thermal dissipation.
• High noise immunity characteristic of CMOS devices ensures stable operation in electrically noisy environments.
• The high-impedance output state provides the means to implement wired-OR or bus-oriented configurations.

The MC74ACT257NG is delivered in a 16-pin DIP package, which is conducive to easy insertion in a variety of socket or board configurations. Its robust design ensures reliable operation over an extended temperature range, making it suitable for both commercial and industrial applications.

Whether you're designing a complex data routing system or looking for a reliable multiplexer for simpler signal-switching tasks, the MC74ACT257NG from ON Semiconductor is a dependable choice that offers a combination of performance, power efficiency, and versatility.
