Description and Introduction

Octal Bus Transceivers with 3-State Outputs The SN74ABT245B is an octal bus transceiver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Octal Bus Transceiver  
- **Technology:** ABT (Advanced BiCMOS Technology)  
- **Number of Channels:** 8  
- **Voltage Supply Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Type:** 3-State  
- **Propagation Delay Time:** 3.8ns (max)  
- **High-Level Output Current:** -32mA  
- **Low-Level Output Current:** 64mA  
- **Package Options:** SOIC, SSOP, TSSOP  

### **Descriptions:**  
The SN74ABT245B 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 when high, placing them in a high-impedance state.  

### **Features:**  
- **Bidirectional Voltage Translation:** Supports 5V to 3.3V level shifting.  
- **High-Speed Operation:** Optimized for high-performance systems.  
- **Low Power Consumption:** ABT technology reduces power dissipation.  
- **3-State Outputs:** Allows bus isolation when disabled.  
- **ESD Protection:** Exceeds 2000V per JESD 22-A114.  
- **Latch-Up Performance:** Exceeds 500mA per JESD 78.  

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