ON Semiconductor MC74ACT257MELG Quad 2-Input Multiplexer

The ON Semiconductor MC74ACT257MELG is a high-performance, quad 2-input multiplexer that is designed to select between two sets of four data sources. This versatile integrated circuit (IC) is part of ON Semiconductor's advanced high-speed CMOS (Complementary Metal-Oxide Semiconductor) technology, which provides a robust solution for routing digital signals within a wide array of electronic systems.

This multiplexer IC features four identical 2-input multiplexers with three-state outputs that can be used to pass or block digital signals depending on the control inputs. The MC74ACT257MELG is capable of working with a wide operating voltage range of 4.5V to 5.5V, making it suitable for interfacing with TTL (Transistor-Transistor Logic) levels. This flexibility allows the device to be used in a variety of digital applications, including data routing, signal gating, and function generation.

Each multiplexer on the MC74ACT257MELG has two inputs (A and B), one output (Y), and two control inputs. The control inputs consist of a common enable input (OE) and a select input (S) for each multiplexer. When the enable input is active, the selected input data (A or B) is passed to the output. When the enable input is inactive, the output assumes a high-impedance state, effectively disconnecting the multiplexer from the circuit and allowing for bus-oriented applications.

The MC74ACT257MELG is offered in a SOIC-16 package, providing a compact footprint for space-constrained applications. Its fast switching speeds and low power consumption make it an excellent choice for high-speed data processing and communication systems.

Key features of the MC74ACT257MELG include:

• Quad 2-input multiplexer with three-state outputs
• Wide operating voltage range of 4.5V to 5.5V
• Compatible with TTL levels
• High-impedance state during power down
• SOIC-16 package for space-saving applications
• Industrial operating temperature range

Overall, the ON Semiconductor MC74ACT257MELG is a reliable and efficient solution for designers looking to implement flexible data routing capabilities in their digital systems. Its performance characteristics and ease of use make it a valuable addition to a wide range of electronic designs.
