Description and Introduction

TIME SLOT INTERCHANGE DIGITAL SWITCH 128 x 128 The part **IDT728981J** is a high-speed, low-power **First-In, First-Out (FIFO)** memory device manufactured by **Integrated Device Technology (IDT)**. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Type:** Synchronous FIFO  
- **Organization:** 512 x 18  
- **Data Width:** 18-bit  
- **Operating Voltage:** 5V  
- **Speed Grade:** 25 MHz (40 ns access time)  
- **Package:** 32-pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature:** Commercial (0°C to +70°C)  

### **Descriptions:**  
- Designed for high-speed data buffering applications.  
- Supports synchronous read and write operations.  
- Features programmable flags (Empty, Full, Half-Full) for efficient data management.  
- Low-power CMOS technology for reduced power consumption.  

### **Features:**  
- **Synchronous operation** with independent clock inputs for read and write.  
- **Programmable Almost-Empty (PAE) and Almost-Full (PAF)** flags.  
- **Retransmit capability** for data re-reading.  
- **Master Reset (MR)** for clearing the FIFO.  
- **TTL-compatible** inputs and outputs.  
- **Industrial-standard pinout** for easy integration.  

This FIFO is commonly used in telecommunications, networking, and digital signal processing applications where temporary data storage and transfer are required.
