Description and Introduction

16-Bit Bus Transceiver And Register With 3-State Outputs The SN74ALVCH16646DGGR is a 16-bit bus transceiver and register manufactured by Texas Instruments. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Category:** Logic - Buffers, Drivers, Receivers, Transceivers  
- **Package:** 56-TSSOP  
- **Logic Type:** Transceiver, Non-Inverting  
- **Number of Bits:** 16  
- **Voltage Supply:** 1.65V to 3.6V  
- **Operating Temperature:** -40°C to +85°C  
- **Output Type:** 3-State  
- **Mounting Type:** Surface Mount  
- **Propagation Delay:** 2.3ns (typical) at 3.3V  

### **Descriptions:**  
- The SN74ALVCH16646DGGR is a 16-bit bus transceiver with D-type registers designed for low-voltage (1.65V to 3.6V) applications.  
- It supports bidirectional data flow and features 3-state outputs for bus interfacing.  
- The device includes control inputs for direction selection and output enable.  

### **Features:**  
- **Wide Operating Voltage Range:** 1.65V to 3.6V  
- **Bus Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors  
- **3-State Outputs:** Allows multiple devices to share a common bus  
- **Supports Mixed-Mode Signal Operation:** Compatible with 3.3V and lower voltage systems  
- **ESD Protection:** Exceeds 2000V (HBM) and 1000V (CDM)  
- **Flow-Through Pinout:** Optimized for PCB layout  

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

Application Scenarios & Design Considerations

16-Bit Bus Transceiver And Register With 3-State Outputs

Alternative Part Number

  • 74ALVCH16646DGG --: Same ALVCH 16-bit bus transceiver/register function in a TSSOP-56 package, offered by NXP as a direct functional equivalent.
  • 74ALVCH16646PA --: Equivalent ALVCH 16646 bus transceiver/register with similar voltage range and drive strength, suitable as a drop-in functional replacement.
  • 74ALVCH16646DGV --: ALVCH-series 16-bit transceiver/register from Nexperia with comparable logic family characteristics; verify package and pinout before substitution.
