- **Low-Level Input Voltage (Max):** 0.8V (at VCC = 2V), 1.35V (at VCC = 4.5V)  
- **High-Level Output Current (Max):** -5.2mA (at VCC = 4.5V)  
- **Low-Level Output Current (Max):** 5.2mA (at VCC = 4.5V)  
- **Propagation Delay (Max):** 18ns (at VCC = 4.5V)  
- **Package Type:** SOP-20 (Small Outline Package, 20-pin)  

### **Descriptions:**  
- The **TC74HC245AFW** is an **8-bit bidirectional transceiver** with 3-state outputs.  
- It is designed for **asynchronous communication** between data buses.  
- The direction of data flow is controlled by the **DIR (Direction Control)** input.  
- The **OE (Output Enable)** pin enables/disables the outputs.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by the DIR pin.  
- **3-State Outputs:** Allows bus-oriented applications.  
- **High-Speed Operation:** Optimized for fast signal transmission.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **Wide Operating Voltage Range:** Supports 2V to 6V operation.  
- **TTL-Compatible Inputs:** Ensures compatibility with TTL logic levels.  

This device is commonly used in **bus interface, data buffering, and level-shifting applications**.
