### **Descriptions:**  
The SN74LS245NSR is an octal bus transceiver designed for asynchronous two-way communication between data buses. It features separate control inputs for direction (DIR) and output enable (OE), allowing bidirectional data flow.  

### **Features:**  
- **3-State Outputs:** Allows connection to a bus system.  
- **Wide Operating Voltage:** 4.75V to 5.25V.  
- **High-Current Outputs:** Can drive up to 24 mA.  
- **Bidirectional Data Flow:** Controlled by the DIR pin.  
- **Output Enable (OE) Input:** Disables outputs when high.  
- **Low Power Consumption:** Typical ICC of 24 mA.  
- **ESD Protection:** Exceeds 2000V per MIL-STD-883, Method 3015.  

This device is commonly used in bus-oriented systems for data transfer between microprocessors and peripherals.
