Description and Introduction

Octal Bus Transceivers with 3-State Outputs The SN74ABT245BDWR is a bus transceiver manufactured by Texas Instruments. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** Octal Bus Transceiver  
- **Technology:** ABT (Advanced BiCMOS Technology)  
- **Number of Channels:** 8  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Type:** 3-State  
- **Package:** SOIC (DW), 20-pin  
- **Data Rate:** Up to 100 MHz  
- **Input/Output Compatibility:** TTL, 5V CMOS  
- **High-Level Output Current:** -32 mA  
- **Low-Level Output Current:** 64 mA  

### **Descriptions:**  
The SN74ABT245BDWR is an 8-bit bidirectional transceiver designed for asynchronous communication between data buses. It features non-inverting 3-state outputs and is compatible with TTL and 5V CMOS logic levels. The direction of data flow is controlled by the DIR (Direction Control) input, while the OE (Output Enable) input disables the outputs when high.

### **Features:**  
- **Bidirectional Data Flow:** Controlled by DIR pin.  
- **3-State Outputs:** Allows bus isolation when disabled.  
- **High Drive Capability:** Supports heavy bus loads.  
- **Low Power Consumption:** ABT technology reduces power dissipation.  
- **ESD Protection:** Exceeds 2000V per JESD 22-A114.  
- **Latch-Up Performance:** Exceeds 500 mA per JESD 78.
