Description and Introduction

3.3-V ABT 16-Bit Registered Transceivers With 3-State Outputs The SN74LVT16543DL is a 16-bit registered transceiver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Registered Transceiver  
- **Number of Bits:** 16  
- **Voltage Supply Range:** 2.7V to 3.6V  
- **Input/Output Type:** 3.3V TTL-Compatible  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SSOP (DL) - 56-pin  
- **High-Speed Operation:** 3.5ns max propagation delay  
- **Output Drive Capability:** ±24mA at 3.3V  
- **Bus-Hold Data Inputs:** Eliminates need for external pull-up/pull-down resistors  

### **Descriptions:**  
The SN74LVT16543DL is a bidirectional registered transceiver designed for 3.3V operation. It features 16-bit non-inverting data paths with independent registers for A-to-B and B-to-A transfers. It supports live insertion and power-off protection.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by direction control (DIR) and output enable (OE) inputs  
- **Separate Registers for Input and Output:** Allows independent data latching  
- **Bus-Hold on Data Inputs:** Maintains valid logic levels  
- **Power-Up High-Impedance State:** Prevents bus contention  
- **ESD Protection:** Exceeds 2000V per JESD 22  

This device is commonly used in data communication and buffering applications.
