Description and Introduction

3.3-V ABT 16-Bit Registered Transceivers With 3-State Outputs The SN74LVTH16543DGGR is a 16-bit bus transceiver and register manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Technology Family:** LVTH (Low-Voltage BiCMOS Technology with 3.3V TTL-compatible inputs/outputs)  
- **Supply Voltage Range:** 2.7V to 3.6V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package Type:** TSSOP (DGGR) – 56-pin  
- **Logic Type:** Transceiver, Non-Inverting  
- **Number of Bits:** 16  
- **Output Type:** 3-State  
- **Propagation Delay:** 3.6 ns (max) at 3.3V  
- **I/O Type:** TTL-Compatible  

### **Descriptions:**
- The SN74LVTH16543DGGR is a 16-bit transceiver with D-type latches and flip-flops, designed for low-voltage (3.3V) operation.  
- It supports bidirectional data flow between A and B ports, controlled by output-enable (OE) and direction-control (DIR) inputs.  
- The device includes 16 edge-triggered flip-flops and 16 transparent latches for data storage.  

### **Features:**
- **Bus Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **3.3V Tolerant Inputs:** Allows interfacing with 5V logic levels.  
- **High Drive Outputs (±32 mA at 3V).**  
- **Supports Live Insertion.**  
- **ESD Protection:** Exceeds 2000V per JESD 22.  
- **Flow-Through Pinout:** Optimized for PCB layout.  

This device is commonly used in data communication, networking, and computing applications requiring bidirectional data transfer.
