ON Semiconductor MC74ACT157DG: Quad 2-Input Multiplexer

The MC74ACT157DG from ON Semiconductor is a high-performance, quad 2-input multiplexer that is part of the advanced high-speed CMOS family. This integrated circuit is designed to select one of two inputs for each multiplexer by applying a common select input, making it an essential component in digital systems where multiple data sources need to be routed to a single output line.

Key Features

• Logic Type: Multiplexer
• Number of Circuits: Four 2:1 multiplexers
• Output Current: High 24mA, Low 24mA
• Propagation Delay Time: 9ns at 5V
• Operating Temperature: -55°C to 125°C
• Mounting Type: Surface Mount
• Package / Case: SOIC-16
• Supply Voltage: 4.5V to 5.5V

The device features a common enable input that, when held low, effectively turns off all multiplexers, providing an additional layer of control. This function is particularly useful for reducing power consumption or for implementing a 'data hold' state during system maintenance or troubleshooting.

With its fast propagation delay and high current output, the MC74ACT157DG is suitable for a variety of applications that require quick and reliable switching between data sources. This includes data routing in communication systems, address multiplexing in memory selection circuits, and signal gating in mixed digital/analog environments.

The device is fabricated with silicon gate CMOS technology, ensuring minimal power consumption during operation. Additionally, its SOIC-16 package is compact and suitable for space-constrained applications while providing industry-standard soldering footprint.

ON Semiconductor's commitment to quality ensures that the MC74ACT157DG meets stringent standards, providing reliable performance in commercial, industrial, and military-grade environments. Whether you're designing complex computing systems, sophisticated instrumentation, or consumer electronics, the MC74ACT157DG offers a versatile and efficient solution for your multiplexing needs.
