Description and Introduction

3.3-V ABT OCTAL BUS TRANSCEIVERS AND REGISTERS WITH 3-STATE OUTPUTS The SN74LVT646DW is a 3.3V ABT 16-bit bus transceiver and register manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Bus Transceiver, Non-Inverting  
- **Voltage Supply:** 3V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Bits:** 16  
- **Output Type:** 3-State  
- **Package / Case:** SOIC-24  
- **Mounting Type:** Surface Mount  
- **Propagation Delay Time:** 3.5ns (max)  
- **High-Level Output Current:** -32mA  
- **Low-Level Output Current:** 64mA  

### **Descriptions:**  
The SN74LVT646DW combines D-type latches and D-type flip-flops to allow data flow in transparent, latched, or clocked modes. It is designed for asynchronous communication between data buses and features 3-state outputs for bus-oriented applications.  

### **Features:**  
- **3.3V Operation** with 5V Tolerant Inputs/Outputs  
- **Bus Hold** on Data Inputs Eliminates Need for External Pull-Up/Pull-Down Resistors  
- **Flow-Through Pinout** Optimizes PCB Layout  
- **Supports Mixed-Mode Signal Operation** (5V Input and Output Voltages with 3.3V VCC)  
- **Latch-Up Performance Exceeds 500mA Per JESD 17**  
- **ESD Protection Exceeds JESD 22** (2000V Human-Body Model, 200V Machine Model)  

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