Description and Introduction

Comparator With Output Voltage-Level Translation 6-SOT -40 to 85 The part **TXS03121DRLR** is manufactured by **Texas Instruments (TI)**.  

### **Specifications:**  
- **Type:** 4-Bit Bidirectional Voltage-Level Translator  
- **Voltage Range (VCCA):** 1.2V to 3.6V  
- **Voltage Range (VCCB):** 1.65V to 5.5V  
- **Data Rate:** Up to 100 Mbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin VSSOP (DRL)  

### **Descriptions & Features:**  
- Bidirectional voltage translation between different logic levels  
- Automatic direction sensing (no direction control signal needed)  
- Supports mixed-mode signal operation (open-drain and push-pull)  
- Low power consumption  
- ESD protection exceeding 8 kV (HBM)  
- No power sequencing requirements (VCCA or VCCB can be ramped first)  
- Suitable for I²C, SPI, UART, and other digital interfaces  

This part is commonly used in applications requiring voltage-level translation between low-voltage and higher-voltage systems.

Application Scenarios & Design Considerations

Alternative Part Number

  • SN74LVC1T45DRLR --: Single-bit dual-supply voltage-level translator in the same SOT-563/DRL package, functionally similar to the TXS03121 and widely available.
  • 74LVC1T45GW,125 --: Pin-compatible single-bit dual-supply level translator from a different series, suitable as a functional drop-in with similar voltage translation behavior.
  • SN74AXC1T45DRLR --: Single-bit dual-supply translator in the same DRL package with improved low-voltage operation, offering a close functional match.
