ON Semiconductor MC74ACT541DTR2G Octal Buffer/Line Driver

The MC74ACT541DTR2G from ON Semiconductor is a high-performance, octal buffer and line driver designed to interface with 8-bit microprocessors and bus-oriented systems. This integrated circuit is a part of the ACT series, which is known for its high-speed operation while maintaining the CMOS low power consumption. The device is optimized to effectively drive bus lines or buffer memory address registers, providing a high degree of flexibility within digital systems.

Constructed with BiCMOS technology, the MC74ACT541DTR2G offers robust characteristics that make it suitable for a variety of applications. It features non-inverting buffers with 3-state outputs that can drive bus lines or buffer memory address registers. The 3-state outputs are controlled by two output enable (OE) inputs, which when high, put the outputs into a high impedance state. This feature is crucial for bus-oriented systems, where multiple devices need to share the same bus lines without interfering with each other.

The device is capable of operating over a wide voltage range from 4.5V to 5.5V, making it compatible with TTL levels. Inputs are tolerant to voltages up to 5.5V, allowing for direct interfacing with different logic levels without the need for external components. The MC74ACT541DTR2G also boasts a high noise immunity characteristic of CMOS devices, which is essential for use in electrically noisy environments.

ON Semiconductor has packaged the MC74ACT541DTR2G in a TSSOP-20 (Thin Shrink Small Outline Package), which is ideal for space-constrained applications. The device's package is designed for improved PCB (Printed Circuit Board) layout and enhanced thermal performance. This product is also available in a lead-free version, demonstrating ON Semiconductor's commitment to environmentally friendly and sustainable manufacturing practices.

With its combination of high-speed performance, low power consumption, and robust design, the MC74ACT541DTR2G is an excellent choice for use in a wide range of digital applications, including computing, data communication, and industrial systems.
