Description and Introduction

16-BIT DUAL-SUPPLY BUS TRANSCEIVER WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS The SN74LVCH16T245ZQLR is a 16-bit dual-supply bus transceiver manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** Bus Transceiver  
- **Number of Bits:** 16  
- **Voltage - Supply (VccA):** 1.2V to 3.6V  
- **Voltage - Supply (VccB):** 1.65V to 5.5V  
- **Output Type:** 3-State  
- **Operating Temperature:** -40°C to +85°C  
- **Package / Case:** 56-BGA (MicroStar Junior™)  
- **Mounting Type:** Surface Mount  
- **Features:** Partial Power Down (Ioff), Overvoltage Tolerance, Bus-Hold  

### **Descriptions:**  
- The SN74LVCH16T245ZQLR is a non-inverting, 16-bit bidirectional voltage-level translator with 3-state outputs.  
- It supports mixed-voltage communication between two data buses (A and B) with different voltage levels.  
- The direction control (DIR) pin determines data flow (A to B or B to A).  
- The output enable (OE) pin disables the outputs when high.  

### **Features:**  
- **Dual-Supply Operation:** Allows voltage translation between different supply levels.  
- **Partial Power-Down Protection (Ioff):** Prevents current backflow when powered off.  
- **Bus-Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **Overvoltage-Tolerant Inputs/Outputs:** Supports voltages up to 5.5V.  
- **3-State Outputs:** Allows multiple devices to share a common bus.  
- **Low Power Consumption:** Optimized for battery-operated applications.  

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