Description and Introduction

HIGH-SPEED 2K x 8 DUAL-PORT STATIC RAM WITH INTERRUPTS The **IDT7142SA55J** is a high-speed, low-power **dual-port static RAM (SRAM)** manufactured by **Integrated Device Technology (IDT)**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Density:** 16K (2K x 8-bit)  
- **Speed:** 55 ns access time  
- **Voltage Supply:** 5V ±10%  
- **Operating Current:** 120 mA (typical)  
- **Standby Current:** 10 mA (typical)  
- **Package:** 48-pin PLCC (Plastic Leaded Chip Carrier)  
- **Temperature Range:** Commercial (0°C to +70°C)  

### **Descriptions:**
- **Dual-Port Architecture:** Allows simultaneous access from both ports for high-speed data transfer.  
- **Asynchronous Operation:** No clock required for read/write operations.  
- **Bus Matching:** 8-bit data bus width for compatibility with microprocessors.  
- **Semaphore Signaling:** Supports hardware-based arbitration for shared resource management.  
- **Interrupt Control:** Features BUSY and INT flags for port arbitration and communication.  

### **Features:**
- **True Dual-Port Operation:** Independent read/write access on both ports.  
- **Low Power Consumption:** CMOS technology for reduced power usage.  
- **High-Speed Performance:** 55 ns access time for fast data processing.  
- **Automatic Power-Down:** Reduces power in standby mode.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Industrial-Grade Reliability:** Robust design for stable operation.  

This device is commonly used in applications requiring high-speed data buffering, such as communication systems, networking equipment, and multiprocessor systems.  

(Note: Always verify datasheets for the latest specifications.)
