HIGH-SPEED 4K x 8 DUAL-PORT STATIC RAM WITH SEMAPHORE The **IDT71342LA55J** is a high-speed, low-power **4K x 16-bit dual-port static RAM (SRAM)** manufactured by **Integrated Device Technology (IDT)**.  

### **Key Specifications:**  
- **Organization:** 4K x 16-bit (65,536 bits)  
- **Access Time:** 55 ns  
- **Operating Voltage:** 5V ±10%  
- **Power Consumption:**  
  - Active: 1,500 mW (max)  
  - Standby: 55 mW (max)  
- **Package:** 68-pin PLCC (Plastic Leaded Chip Carrier)  
- **Temperature Range:** Commercial (0°C to +70°C)  

### **Features:**  
- **True Dual-Port Operation:** Allows simultaneous access from both ports.  
- **Semaphores:** Hardware-based semaphore logic for inter-processor communication.  
- **Bus Arbitration:** On-chip arbitration logic prevents contention.  
- **Interrupt Flags:** Supports mailbox communication via interrupt generation.  
- **Fully Static Operation:** No refresh cycles required.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **High-Speed Performance:** Suitable for real-time data sharing applications.  

### **Applications:**  
- Multi-processor systems  
- Communication buffers  
- Data logging systems  
- Dual-port memory expansion  

This device is designed for high-reliability applications requiring fast, non-blocking access from two independent ports.
