Description and Introduction

Octal Bus Transceivers With 3-State Outputs The SN74ALS645ADW is a 3-state octal bus transceiver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** Octal Bus Transceiver  
- **Technology:** Advanced Low-Power Schottky (ALS)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** SOIC (DW)  
- **Number of Pins:** 20  
- **Data Rate:** Up to 50 MHz  
- **Output Drive Capability:** ±24 mA  
- **Propagation Delay:** 10 ns (max)  

### **Descriptions:**  
- The SN74ALS645ADW is designed for bidirectional data transfer between buses.  
- It features 3-state outputs for bus-oriented applications.  
- Direction control (DIR) determines data flow (A to B or B to A).  
- Output enable (OE) allows high-impedance state for bus isolation.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by DIR input.  
- **3-State Outputs:** Allows bus isolation when disabled.  
- **Wide Operating Voltage:** 4.5V to 5.5V.  
- **High-Speed Operation:** Optimized for 50 MHz performance.  
- **Low Power Consumption:** ALS technology reduces power usage.  
- **ESD Protection:** Exceeds 2000V per JESD 22-A114.
