- **Input Capacitance:** 3 pF (typical)  
- **Package / Case:** SSOP-20  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
The SN74HCT245DBRG4 is an octal bus transceiver designed for asynchronous communication between data buses. It features 3-state outputs for bus-oriented applications and bidirectional data flow controlled by the direction (DIR) input.  

### **Features:**  
- **Bidirectional Voltage Translation:** Allows interfacing between 5V and lower voltage systems.  
- **3-State Outputs:** Supports bus sharing with multiple devices.  
- **High-Current Outputs:** Capable of driving up to 15 LSTTL loads.  
- **Low Power Consumption:** Typical ICC of 80 µA.  
- **ESD Protection:** Exceeds 2000V per JESD 22.  

This device is commonly used in data communication systems, microprocessor interfaces, and other digital logic applications.
