Description and Introduction

1-Bit To 2-Bit Address Driver With 3-State Outputs The SN74ALVCH162830GR is a 20-bit universal bus driver manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** Buffer/Driver  
- **Number of Bits:** 20  
- **Supply Voltage Range:** 1.65V to 3.6V  
- **Input/Output Type:** 3-State  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TSSOP (56-pin)  
- **Output Drive Capability:** ±24mA at 3.3V  
- **Propagation Delay:** 2.5ns (typical) at 3.3V  
- **Input Capacitance:** 4pF (typical)  
- **ESD Protection:** Exceeds 2000V (HBM)  

### **Description:**  
The SN74ALVCH162830GR is a high-performance, low-voltage CMOS 20-bit universal bus driver with 3-state outputs. It is designed for 1.65V to 3.6V VCC operation and supports partial-power-down mode using Ioff circuitry.  

### **Features:**  
- **Wide Operating Voltage Range:** 1.65V to 3.6V  
- **Bus Hold on Data Inputs:** Eliminates need for external pull-up/pull-down resistors  
- **3-State Outputs:** Allows multiple drivers to share a common bus  
- **Ioff Supports Partial-Power-Down Mode:** Protects circuits when powered off  
- **Balanced Propagation Delays:** Ensures signal integrity  
- **High Drive Outputs (±24mA at 3.3V):** Suitable for driving heavy loads  
- **ESD Protection:** Robust against electrostatic discharge  

This device is commonly used in data communication systems, networking equipment, and other applications requiring high-speed buffering and signal driving.

Application Scenarios & Design Considerations

1-Bit To 2-Bit Address Driver With 3-State Outputs

Alternative Part Number

  • 74ALVCH162830PAG --: Same ALVCH162830 function (16-bit registered buffer) from a different vendor with a distinct naming prefix, pin-compatible TSSOP package.
  • PI74ALVCH162830A --: Direct functional equivalent 16-bit ALVCH registered buffer, different series prefix makes it clearly distinguishable from the TI part.
  • 74ALVCH162830DGG --: Equivalent ALVCH162830 registered buffer in TSSOP, alternate vendor with different naming convention for a drop-in functional replacement.
  • 74ALVCH162830T --: Alternative ALVCH-family 16-bit bus device with comparable logic function and package options for board-level replacement.
