Description and Introduction

3.3-V ABT Octal Registered Transceivers With 3-State Outputs The SN74LVT543 is a 16-bit registered transceiver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Registered Transceiver  
- **Technology:** LVT (Low-Voltage BiCMOS)  
- **Number of Bits:** 16  
- **Voltage Supply Range:** 2.7V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input/Output Type:** 3.3V TTL-Compatible  
- **Propagation Delay:** Typically 3.5 ns  
- **Output Drive Capability:** ±24 mA  
- **Package Options:** 48-pin SSOP, TSSOP  

### **Descriptions:**  
The SN74LVT543 is designed for bidirectional data transfer between buses. It features registered inputs and outputs, ensuring synchronous data transfer with clock control. It is optimized for 3.3V operation while maintaining compatibility with 5V TTL levels.  

### **Features:**  
- **Bidirectional Data Flow** with separate input and output registers  
- **3-State Outputs** for bus-oriented applications  
- **Flow-Through Pinout** for optimized PCB layout  
- **Bus-Hold Data Inputs** eliminate the need for external pull-up/pull-down resistors  
- **ESD Protection** exceeds 2000V per JESD 22  
- **Latch-Up Performance** exceeds 250 mA per JESD 17  

This device is commonly used in data communication, networking, and computing systems requiring high-speed, low-power data transfer.
