Description and Introduction

4-Bit Bidirectional Voltage-Level Shifter with Auto Direction Sensing and +/-15 kV ESD Protect 12-BGA MICROSTAR JUNIOR -40 to 85 The TXB0104ZXUR is a 4-bit bidirectional voltage-level translator from Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Manufacturer:**  
Texas Instruments (TI)  

### **Part Number:**  
TXB0104ZXUR  

### **Description:**  
The TXB0104ZXUR is a 4-bit, non-inverting, bidirectional voltage-level translator designed for asynchronous communication between devices operating at different voltage levels. It automatically detects and translates signals between two voltage domains (1.2V to 3.6V on either side).  

### **Key Features:**  
- **Bidirectional Translation:** No direction control signal required.  
- **Voltage Range:**  
  - **Port A (VCCA):** 1.2V to 3.6V  
  - **Port B (VCCB):** 1.2V to 3.6V  
- **Data Rate:** Up to 100 Mbps (push-pull) or 24 Mbps (open-drain).  
- **Automatic Direction Sensing:** No need for a direction control pin.  
- **No Power-Supply Sequencing Required:** VCCA or VCCB can be powered first.  
- **ESD Protection:** Exceeds 2000V (HBM) and 1000V (CDM).  
- **Package:** 12-pin UQFN (ZXU package).  

### **Applications:**  
- Communication between low-voltage microcontrollers and higher-voltage peripherals.  
- Level shifting for I²C, SPI, UART, and other digital interfaces.  
- Mixed-voltage systems in consumer electronics, IoT, and industrial applications.  

### **Additional Notes:**  
- Supports partial power-down mode (I/O pins become high-impedance when either VCCA or VCCB is off).  
- Does not require external pull-up or pull-down resistors for push-pull applications.  

For detailed electrical characteristics and timing diagrams, refer to the official TI datasheet.
