Description and Introduction

2.5-V/3.3-V 16-Bit Buffers/Drivers With 3-State Outputs The SN74ALVTH162244GR is a 16-bit buffer/driver manufactured by Texas Instruments (TEXAS). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Technology:** ALVTH (Advanced Low-Voltage BiCMOS Technology)  
- **Number of Bits:** 16  
- **Logic Type:** Buffer/Line Driver  
- **Supply Voltage Range:** 2.3V to 3.6V  
- **Output Type:** 3-State  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TSSOP (Thin Shrink Small Outline Package)  
- **Package Pins:** 48  
- **Input/Output Compatibility:** 5V Tolerant Inputs  
- **Propagation Delay:** Typically 3.1 ns at 3.3V  

### **Descriptions:**
- Designed for low-voltage operation (2.3V to 3.6V).  
- Supports partial power-down mode with bus hold on data inputs.  
- Suitable for driving high-capacitive loads and transmission lines.  

### **Features:**
- **Bus Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **3-State Outputs:** Allows multiple outputs to be connected to a common bus.  
- **5V Tolerant Inputs:** Enables interfacing with 5V logic levels.  
- **High Drive Outputs (±12 mA at 3V).**  
- **ESD Protection:** Exceeds 2000V per JESD 22.  

This device is commonly used in memory interfaces, networking, and telecommunications applications.

Application Scenarios & Design Considerations

2.5-V/3.3-V 16-Bit Buffers/Drivers With 3-State Outputs

Alternative Part Number

  • 74ALVTH162244DGG --: Same ALVTH 16-bit buffer function with 3-state outputs, different manufacturer and package naming, direct functional equivalent.
  • 74ALVCH162244DG --: Similar 16-bit buffer/driver with 3-state outputs in the ALVCH family; close electrical match though bus-hold differs slightly.
  • 74ALVT162244DGG --: ALVT family 16-bit buffer with 3-state outputs, comparable drive and voltage range, usable as a functional substitute.
  • 74LVTH162244MTD --: LVTH 16-bit buffer with 3-state outputs, comparable low-voltage TTL-compatible logic family and pinout, suitable as a functional substitute.
