Description and Introduction

3.3 V ABT 16-Bit Bus Transceivers and Registers With 3-State Outputs The SN74LVTH16646 is a 16-bit bus transceiver and register manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Bus Transceiver/Register  
- **Number of Bits:** 16  
- **Voltage Supply:** 3.3V (2.7V to 3.6V operating range)  
- **Input/Output Type:** 3.3V TTL-Compatible  
- **High-Speed Operation:** 3.5 ns max propagation delay  
- **Output Drive Capability:** ±12 mA  
- **Bus-Hold Data Inputs:** Eliminates need for external pull-up/pull-down resistors  
- **Power-Up 3-State:** Supports live insertion  
- **ESD Protection:** Exceeds 2000V per JESD 22  

### **Descriptions:**  
The SN74LVTH16646 is a 16-bit bus transceiver with 3-state outputs, designed for low-voltage (3.3V) applications. It combines D-type flip-flops and transceiver functions, allowing bidirectional data flow between buses.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by DIR (Direction Control) input  
- **Output Enable (OE) Input:** Disables outputs when high  
- **Latch Enable (LE) Input:** Allows data storage in registers  
- **3-State Outputs:** Supports bus-oriented applications  
- **Live Insertion Protection:** Prevents bus disturbance during power-up  
- **Bus-Hold Circuitry:** Maintains last valid logic level on floating inputs  

This device is commonly used in data communication systems, networking equipment, and other high-speed digital applications.
