Description and Introduction

8-Bit Dual-Supply Bus Transceiver with Configurable Voltage-Level Shifting and Three-State Outputs 24-VQFN -40 to 85 The SN74LVC8T245RHLR is an 8-bit dual-supply bus transceiver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Technology:** CMOS  
- **Number of Bits:** 8  
- **Voltage Supply (VCC):** 1.65V to 5.5V  
- **Input Voltage (VIN):** 0V to 5.5V  
- **Output Voltage (VOUT):** 0V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** VQFN (RHL) – 24-pin  
- **Data Rate:** Up to 140 Mbps  
- **Direction Control:** DIR pin controls data flow  
- **Output Drive Capability:** ±24mA at 3.3V  
- **ESD Protection:** >2000V (HBM)  

### **Descriptions:**  
- The SN74LVC8T245RHLR is a non-inverting, bidirectional voltage-level translator with 3-state outputs.  
- It allows bidirectional voltage translation between different logic levels (e.g., 1.8V, 2.5V, 3.3V, and 5V).  
- The DIR pin controls data flow direction (A to B or B to A).  
- Supports partial power-down mode (Ioff circuitry disables outputs when VCC is 0V).  

### **Features:**  
- **Wide Voltage Range:** Operates from 1.65V to 5.5V.  
- **Bidirectional Translation:** Enables communication between different voltage domains.  
- **3-State Outputs:** Allows bus isolation.  
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **Robust Design:** High noise immunity and ESD protection.  
- **Hot Insertion Protection:** Supports live insertion without damage.  

This device is commonly used in mixed-voltage systems, such as microcontrollers, FPGAs, and communication interfaces.
