Description and Introduction

CMOS SUPERSYNC FIFOO 8,192 x 18, 16,384 x 18 The IDT72265L20TF is a high-speed, low-power 16K x 18 synchronous FIFO (First-In, First-Out) memory device manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 16K x 18-bit  
- **Operating Voltage:** 3.3V  
- **Speed Grade:** 20ns (50 MHz)  
- **Package:** 64-pin Thin Quad Flat Pack (TQFP)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **I/O Type:** 5V-tolerant inputs  

### **Descriptions:**
- The IDT72265L20TF is a synchronous FIFO designed for high-speed data buffering applications.  
- It supports simultaneous read and write operations with independent clocks.  
- Features programmable Almost Full/Almost Empty flags for flow control.  
- Includes a retransmit capability for data recovery.  

### **Features:**
- **High-Speed Operation:** 20ns access time (50 MHz).  
- **Low Power Consumption:** Optimized for 3.3V operation.  
- **Synchronous Operation:** Independent read and write clocks.  
- **Flag Controls:** Programmable Almost Full/Almost Empty flags.  
- **Retransmit Function:** Allows re-reading of data.  
- **5V-Tolerant Inputs:** Ensures compatibility with 5V systems.  
- **Expandable Depth and Width:** Supports daisy-chaining for larger FIFOs.  

This FIFO is commonly used in networking, telecommunications, and data processing applications requiring high-speed buffering.
