Description and Introduction

Octal Bus Transceiver With 3-State Outputs The SN74LVCR2245AZQNR is a 8-bit bus transceiver manufactured by Texas Instruments (TI). Here are the key specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** Bus Transceiver  
- **Number of Bits:** 8  
- **Voltage - Supply:** 1.65V to 3.6V  
- **Output Type:** 3-State  
- **Operating Temperature:** -40°C to 85°C  
- **Package / Case:** 20-WFBGA, DSBGA  
- **Mounting Type:** Surface Mount  
- **Features:**  
  - Supports mixed-mode signal operation (1.8V, 2.5V, 3.3V)  
  - Partial power-down (Ioff) protection  
  - Bus-hold on data inputs eliminates need for external pull-up/pull-down resistors  
  - Latch-up performance exceeds 250 mA per JESD 17  
  - ESD protection exceeds 2000V (HBM) and 1000V (CDM)  

### **Description:**  
The SN74LVCR2245AZQNR is a bidirectional voltage-level translating transceiver designed for asynchronous communication between data buses. It features 3-state outputs and is optimized for low-voltage (1.65V to 3.6V) applications.  

### **Features:**  
- **Bidirectional Voltage Translation:** Supports mixed-voltage operation (1.8V, 2.5V, 3.3V)  
- **3-State Outputs:** Allows multiple outputs to be connected to a common bus  
- **Bus-Hold Circuitry:** Maintains input levels when inputs are floating  
- **Power-Off Protection (Ioff):** Prevents current backflow when powered down  
- **High-Speed Operation:** Optimized for low-voltage, high-performance applications  
- **ESD Protection:** Robust electrostatic discharge protection  

This device is commonly used in applications requiring voltage-level translation, such as in mixed-voltage systems, networking, and portable electronics.
