ON Semiconductor MC74ACT541MR1 Octal Buffer/Line Driver

The MC74ACT541MR1 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 member of the high-speed CMOS ACT family, which features the robustness of CMOS technology combined with the speed and drive capabilities of bipolar technology.

With its non-inverting buffers, the MC74ACT541MR1 has a wide operating voltage range of 4.5V to 5.5V, making it versatile for use in various digital systems. The device is characterized for operation from -40°C to 85°C, ensuring reliable performance over a broad range of ambient temperatures.

The MC74ACT541MR1 comes in a compact SOP-20 (Small Outline Package) form factor, providing a space-efficient solution for PCB layouts. It is designed with a 3-state output stage, allowing for increased flexibility in bus-oriented applications. When the output enable (OE) input is high, the outputs are in a high-impedance state, which effectively isolates the bus lines.

Key features of the MC74ACT541MR1 include:

• High-speed CMOS technology
• Octal non-inverting buffers with 3-state outputs
• Operating voltage range of 4.5V to 5.5V
• Source/sink current capability of 24 mA at the outputs
• Low input current of 1 µA max
• Improved latch-up immunity
• Low quiescent power consumption

This device is ideal for driving bus lines or buffer memory address registers, offering the high current sinking capability required to drive LEDs and other displays, and the high current sourcing capability necessary for driving several TTL inputs. The MC74ACT541MR1 is also suitable for implementing logic-level conversions from high to low voltage and vice versa, thanks to its high noise immunity and low propagation delay.

Whether used in personal computers, peripherals, networking, or telecommunication systems, the ON Semiconductor MC74ACT541MR1 provides a reliable and efficient solution for digital signal buffering and driving requirements.
