Description and Introduction

Quiet Series Octal Registered Transceiver with 3-STATE Outputs The **74ACTQ543SCX** from National Semiconductor is a high-performance, octal transceiver designed for bidirectional data transfer between buses. This integrated circuit (IC) operates within the **Advanced CMOS Technology (ACTQ)** family, offering enhanced speed and low power consumption, making it ideal for high-speed digital systems.  

Featuring **3-state outputs**, the 74ACTQ543SCX allows multiple devices to share a common bus without interference. It supports **bidirectional data flow**, controlled by separate output-enable (OE) and direction (DIR) inputs, ensuring flexible data routing. With a **wide operating voltage range (4.5V to 5.5V)**, it is compatible with TTL levels, facilitating seamless integration into mixed-voltage systems.  

The device is optimized for **low noise and reduced power dissipation**, critical for high-frequency applications. Its **20-pin surface-mount package (SCX)** ensures compact placement on PCBs, suitable for space-constrained designs.  

Common applications include **data buffering, bus isolation, and interfacing between microprocessors and peripherals**. The 74ACTQ543SCX combines reliability with high-speed performance, making it a preferred choice for engineers working on **computing, telecommunications, and industrial control systems**.  

For detailed specifications, refer to the official datasheet to ensure proper implementation in your circuit design.
