Description and Introduction

Octal latched transceiver with dual enable; 3-state # Introduction to the N74F543D Electronic Component  

The **N74F543D** is a high-performance integrated circuit (IC) belonging to the **74F series** of logic devices. Designed for digital applications, this component functions as an **8-bit transparent latch with 3-state outputs**, making it suitable for data buffering, storage, and bus interfacing in microprocessor-based systems.  

Featuring **low-power Schottky (LS) technology**, the N74F543D ensures fast switching speeds while maintaining efficient power consumption. Its **3-state outputs** allow multiple devices to share a common bus without interference, enhancing system flexibility. The latch operates in transparent mode when the enable (EN) input is active, allowing data to pass directly from input to output. When disabled, the outputs enter a high-impedance state, effectively isolating the device from the bus.  

Key specifications include a **wide operating voltage range**, robust noise immunity, and compatibility with **TTL logic levels**, ensuring reliable integration into various digital circuits. The N74F543D is commonly used in **memory addressing, data routing, and I/O expansion** applications.  

Packaged in a **DIP (Dual In-line Package)** or **SOIC (Small Outline IC)**, the N74F543D is widely available and remains a dependable choice for engineers designing high-speed digital systems. Its balance of speed, power efficiency, and versatility makes it a valuable component in modern electronics.

Application Scenarios & Design Considerations

Octal latched transceiver with dual enable; 3-state

Alternative Part Number

  • SN74F543DW --: Same 74F543 octal registered transceiver function in a SOIC-24 package, widely available and pin-compatible replacement.
  • 74F543D --: NXP continues the former Philips 74F logic line, offering the same F543 device in the same D (SOIC) package.
  • MC74F543DW --: Alternative 74F543 octal registered transceiver from a second source, matching function and SOIC-24 footprint.
