### **Specifications:**
- **Manufacturer:** MOT (Motorola)  
- **Part Number:** SN54LS170J  
- **Technology:** LS-TTL (Low-Power Schottky TTL)  
- **Package:** Ceramic DIP (Dual In-line Package)  
- **Operating Temperature Range:** -55°C to +125°C (Military-grade)  
- **Supply Voltage (Vcc):** 4.75V to 5.25V  
- **Logic Family:** 54LS (Military-grade low-power Schottky)  

### **Descriptions:**
- The SN54LS170J is a **4x4 register file** with open-collector outputs.  
- It provides **non-destructive read** and **destructive write** operations.  
- Designed for **military and high-reliability applications** due to its extended temperature range.  
- Features **16 storage cells** (4 words × 4 bits each).  

### **Features:**
- **4-bit word width** with **4-word storage capacity**.  
- **Open-collector outputs** for bus-oriented applications.  
- **Three-state outputs** for bus sharing.
