ON Semiconductor MC74ACT157DTR2G Multiplexer

The MC74ACT157DTR2G is a high-performance, quad 2-input multiplexer from ON Semiconductor that combines low power consumption with high-speed operation. This device is part of the AC/ACT family, which is designed to operate over a broad range of supply voltages with compatible speeds to the AS/ALS series of products. The MC74ACT157DTR2G is characterized for operation from -40°C to 85°C, making it suitable for industrial applications where temperature resilience is essential.

This multiplexer features four identical 2-input multiplexers with 3-state outputs that can interface directly with the bus-organized system's data lines. Each multiplexer has two select inputs (A and B), an enable input (E\), and four sets of inputs (I0 and I1). When the enable input (E\) is held high, the outputs are effectively in a high impedance state, which allows for multiple outputs to be connected together without the risk of high-current bus contention.

The MC74ACT157DTR2G has a wide operating voltage range of 4.5V to 5.5V, and it is TTL-compatible, which makes it easy to interface with other TTL logic families. The device's fast switching speeds and low quiescent current make it an excellent choice for high-speed data processing and communication systems.

The packaging of the MC74ACT157DTR2G is in a TSSOP-16 (Thin Shrink Small Outline Package) form factor, which is ideal for space-constrained applications, while still providing excellent thermal performance. This product is also available in tape and reel packaging, which facilitates automated assembly processes and is suitable for high-volume production environments.

ON Semiconductor's commitment to quality ensures that the MC74ACT157DTR2G multiplexer is a reliable component for designers looking to create efficient and high-performing electronic systems. Whether used in data acquisition systems, signal routing applications, or as a part of a complex digital logic circuit, the MC74ACT157DTR2G is an excellent choice for multiplexing needs.
