- **Propagation Delay (Max):** 7.5 ns (typical)  
- **High-Level Output Current:** -15 mA  
- **Low-Level Output Current:** 48 mA  

### **Descriptions:**  
The SN74AS245 is a bidirectional octal bus transceiver designed for asynchronous communication between data buses. It features non-inverting 3-state outputs and is optimized for high-speed operation with improved power efficiency compared to standard Schottky TTL.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by DIR (Direction) input.  
- **3-State Outputs:** Allows connection to a shared bus.  
- **High-Speed Operation:** Advanced Schottky process for fast switching.  
- **Wide Operating Voltage:** Compatible with 5V systems.  
- **Output Drive Capability:** Supports high-current sinking/sourcing.  
- **ESD Protection:** Exceeds 2000V per JESD 22-A114.  

This device is commonly used in data transmission, buffering, and bus isolation applications.  

(Note: Always refer to the latest datasheet for detailed electrical characteristics and application guidelines.)
