Description and Introduction

Octal Bus Transceivers With 3-State Outputs The SN74ABTH245DW is a bus transceiver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Technology Family:** ABT  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Number of Channels:** 8  
- **Logic Type:** Octal Bus Transceiver  
- **Output Type:** 3-State  
- **Package / Case:** SOIC-20 (DW)  
- **Propagation Delay Time:** 3.5 ns (typical)  
- **High-Level Output Current:** -32 mA  
- **Low-Level Output Current:** 64 mA  

### **Description:**  
The SN74ABTH245DW is an octal bus transceiver designed for asynchronous communication between data buses. It features non-inverting 3-state outputs and is compatible with TTL voltage levels. The direction of data flow is controlled by the DIR (direction) input, while the OE (output enable) input disables the outputs for bus isolation.

### **Features:**  
- **Bi-Directional Data Flow:** Controlled by DIR input.  
- **3-State Outputs:** Allows bus isolation when OE is high.  
- **High-Speed Operation:** Typical propagation delay of 3.5 ns.  
- **TTL-Compatible Inputs:** Works with TTL logic levels.  
- **Bus-Hold Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **ESD Protection:** Exceeds 2000V per JESD 22-A114.  

This device is commonly used in data communication systems, networking equipment, and other applications requiring bidirectional data transfer.
