Description and Introduction

Dual-Bit Dual-Supply Bus Transceiver with Configurable Voltage Translation and 3-State Outputs ### **SN74AVC2T45DCTR (Manufacturer: Texas Instruments - TI)**  

#### **Specifications:**  
- **Type:** Dual-Bit, Dual-Supply Bus Transceiver  
- **Technology:** AVC (Advanced Very-Low-Voltage CMOS)  
- **Voltage Range (VCC):** 1.2V to 3.6V  
- **Data Rate:** Up to 380 Mbps  
- **Number of Channels:** 2 (Dual-Bit)  
- **Logic Level Translation:** Bidirectional (1.2V ↔ 1.8V ↔ 2.5V ↔ 3.3V)  
- **Input/Output Type:** 3-State  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin SM8 (DCTR - TSSOP)  

#### **Descriptions:**  
The **SN74AVC2T45DCTR** is a dual-bit, dual-supply non-inverting bus transceiver designed for asynchronous communication between data buses operating at different voltage levels (1.2V to 3.6V). It features automatic direction sensing and supports bidirectional voltage translation without requiring a direction control signal.  

#### **Features:**  
- **Wide Voltage Range:** Supports 1.2V to 3.6V on both ports (VCCA and VCCB).  
- **Bidirectional Level Shifting:** Enables seamless translation between different voltage domains.  
- **High-Speed Operation:** Supports data rates up to 380 Mbps.  
- **Low Power Consumption:** Optimized for power-sensitive applications.  
- **3-State Outputs:** Allows bus isolation when disabled.  
- **No Direction Control Needed:** Auto-sensing eliminates the need for a DIR pin.  
- **ESD Protection:** Exceeds 2000V (HBM) for robust performance.  
- **Small Footprint:** 8-pin TSSOP package for space-constrained designs.  

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