ON Semiconductor 74ACT157 Quad 2-Input Multiplexer

The ON Semiconductor 74ACT157 is a high-performance, quad 2-input multiplexer that offers the functionality of four individual 2-input multiplexers in a single package. This integrated circuit is designed to be used in applications where the selection of data sources or routing of data lines is required. It is an essential component for digital systems that need to manage multiple input signals and direct them to a single output line.

Key Features:

• Logic Type: 2-Input Multiplexer
• Number of Circuits: Four
• Output Current: High 24mA, Low 24mA
• Propagation Delay Time: 8.5ns at 5V
• Operating Voltage Range: 4.5V to 5.5V
• Operating Temperature Range: -40°C to 85°C
• Package / Case: Various options available

The 74ACT157 features four identical 2-input multiplexers with common select and enable inputs. Each multiplexer has two data inputs (A and B), one output (Y), and an enable input (G). The select input (S) determines which of the data inputs is connected to the output. When the enable input is low, the multiplexer is active, and the data on the selected input is passed through to the output. If the enable input is high, the output is disabled and remains in a high-impedance state, allowing for the connection of multiple outputs to a common bus without interference.

This device is fabricated with advanced CMOS technology to achieve high-speed operation while maintaining low power consumption. The 74ACT157 is compatible with TTL levels and can drive up to 15 LSTTL loads. Its fast propagation delay and high current drive make it suitable for high-speed data transmission and processing applications.

Available in a variety of package options, including DIP, SOIC, TSSOP, and other surface-mount configurations, the 74ACT157 from ON Semiconductor is versatile for both prototyping and mass production. It is ideal for use in data multiplexing, signal gating, and as a function generator in a wide range of digital applications such as computers, communication equipment, and control systems.

With its robust performance characteristics and ON Semiconductor's commitment to quality, the 74ACT157 is a reliable choice for designers looking to implement efficient data routing solutions in their digital systems.
