- **Low-Level Output Current:** 24mA  
- **Package Options:** 20-pin DIP, SOIC  

### **Descriptions:**
The SN74ALS641A is an octal bus transceiver designed for bidirectional data communication between buses. It features non-inverting 3-state outputs and is commonly used in bus-oriented systems where data flow direction is controlled by a direction (DIR) input.

### **Features:**
- **Bidirectional Data Flow:** Controlled by DIR input.  
- **3-State Outputs:** Allows connection to a bus system.  
- **High Drive Capability:** Supports bus loading requirements.  
- **Low Power Consumption:** ALS technology ensures reduced power usage compared to standard TTL.  
- **Wide Operating Voltage:** Compatible with 5V systems.  
- **ESD Protection:** Provides improved reliability.
