Description and Introduction

1-BIT DUAL SUPPLY BUS BUFFER LEVEL TRANSLATOR WITH A SIDE SERIES RESISTOR The part **ST1G3234BJR** is a **1.5 Ohm Ron, 4-bit, 2.3V to 5.5V, bidirectional voltage level translator** manufactured by **STMicroelectronics (STM)**.  

### **Specifications:**  
- **Type:** Bidirectional voltage level translator  
- **Number of Bits:** 4-bit  
- **Voltage Range:** 2.3V to 5.5V  
- **On-Resistance (Ron):** 1.5 Ohm (typical)  
- **Supply Voltage (VCC):** 1.65V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** **BJR** (likely a small form factor, such as UQFN or similar)  
- **Low Power Consumption:** Suitable for battery-operated devices  
- **Bidirectional Translation:** Allows voltage level shifting in both directions  

### **Features:**  
- **Wide Voltage Range:** Supports translation between 2.3V and 5.5V  
- **Low On-Resistance:** Ensures minimal signal distortion  
- **Automatic Direction Sensing:** No need for a direction control pin  
- **High-Speed Operation:** Suitable for I²C, SPI, and other digital interfaces  
- **ESD Protection:** Enhanced electrostatic discharge protection  

This part is commonly used in applications requiring voltage level shifting, such as interfacing between different logic levels in microcontrollers, sensors, and communication buses.  

Would you like additional details on pin configuration or application notes?
