Description and Introduction

Octal Bus Transceivers with 3-State Outputs The SN74ABT245BDBR is a bidirectional octal transceiver manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features:

### **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  
- **Package:** SSOP (DBR), 20-pin  
- **Data Rate:** Up to 100MHz  
- **Input/Output Compatibility:** TTL, 5V CMOS  

### **Descriptions:**  
- The SN74ABT245BDBR is a bidirectional transceiver designed for asynchronous communication between data buses.  
- It allows data transmission in both directions (A to B or B to A) based on the direction control input (DIR).  
- The output enable (OE) pin controls the outputs, allowing them to be placed in a high-impedance state.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by the DIR pin.  
- **3-State Outputs:** Supports bus-oriented applications.  
- **High-Speed Operation:** Optimized for 5V systems.  
- **Low Power Consumption:** ABT technology reduces power dissipation.  
- **ESD Protection:** Exceeds 2000V per JESD 22.  
- **Latch-Up Performance:** Exceeds 500mA per JESD 78.  

This device is commonly used in data buffering, bus isolation, and level translation in digital systems.
