Description and Introduction

3.3-V ABT Octal Bus Transceivers With 3-State Outputs The SN74LVTH245APW is a 3.3V ABT octal bus transceiver manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Technology Family:** LVTH (Low-Voltage BiCMOS Technology)  
- **Supply Voltage Range:** 2.7V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Channels:** 8 (Octal)  
- **Logic Type:** Transceiver, Non-Inverting  
- **Output Type:** 3-State  
- **Package Type:** TSSOP (PW)  
- **Package Pins:** 20  
- **High-Level Output Current:** -32 mA  
- **Low-Level Output Current:** 64 mA  
- **Propagation Delay Time:** 3.8 ns (max) at 3.3V  
- **I/O Compatibility:** 5V Tolerant Inputs  

### **Descriptions:**  
The SN74LVTH245APW is a bidirectional octal bus transceiver designed for asynchronous communication between data buses. It features 3-state outputs and is optimized for low-voltage (3.3V) operation while maintaining 5V input tolerance. It includes direction control (DIR) and output enable (OE) inputs for managing data flow.  

### **Features:**  
- **Bidirectional Voltage Translation:** Supports mixed 3.3V and 5V systems  
- **3-State Outputs:** Allows multiple devices to share a common bus  
- **Bus-Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors  
- **Live Insertion Protection:** Supports hot-plugging applications  
- **ESD Protection:** Exceeds 2000V per JESD 22

Description and Introduction

3.3-V ABT Octal Bus Transceivers With 3-State Outputs The SN74LVTH245APW is a 3.3V ABT octal bus transceiver with 3-state outputs, manufactured by Texas Instruments.  

### **Specifications:**  
- **Logic Type:** Octal Bus Transceiver  
- **Voltage Supply:** 3.3V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Channels:** 8  
- **Output Type:** 3-State  
- **Package Type:** TSSOP-20  
- **High-Level Output Current:** -32 mA  
- **Low-Level Output Current:** 64 mA  
- **Propagation Delay Time:** 3.5 ns (max)  
- **Input/Output Compatibility:** 5V-Tolerant Inputs  

### **Description:**  
The SN74LVTH245APW is designed for asynchronous communication between data buses. It allows bidirectional data flow from A to B or B to A, depending on the direction control input (DIR). The output-enable (OE) input disables the outputs for isolation.  

### **Features:**  
- Supports mixed-mode signal operation (5V input and 3.3V output)  
- Bus-hold on data inputs eliminates the need for external pull-up/pull-down resistors  
- Latch-up performance exceeds 500 mA per JESD 17  
- ESD protection exceeds 2000 V per MIL-STD-883, Method 3015  
- Available in TSSOP-20 package  

This device is commonly used in data communication systems, networking equipment, and industrial applications.
