Description and Introduction

CMOS ASYNCHRONOUS FIFO 2048 x 9, 4096 x 9, 8192 x 9 and 16384 x 9 The IDT7205L50J is a high-speed, low-power 16K x 9 asynchronous FIFO (First-In, First-Out) memory device manufactured by Integrated Device Technology (IDT).  

### **Specifications:**  
- **Organization:** 16K x 9 (16,384 words x 9 bits)  
- **Speed:** 50 MHz (L50J variant)  
- **Operating Voltage:** 5V  
- **Access Time:** 20 ns (max)  
- **Power Consumption:** Low power CMOS technology  
- **Package:** 32-pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  

### **Descriptions and Features:**  
- **Asynchronous FIFO:** Independent read and write clocks  
- **Full and Empty Flags:** Indicates FIFO status  
- **Half-Full Flag:** Optional midpoint indicator  
- **Retransmit Function:** Allows resetting the read pointer to the start  
- **Expandable Depth and Width:** Can be cascaded for larger FIFOs  
- **TTL-Compatible Inputs and Outputs:** Ensures compatibility with standard logic levels  
- **High-Speed Operation:** Suitable for buffering in high-performance systems  
- **Low Standby Power:** Reduces power consumption when idle  

The IDT7205L50J is commonly used in data buffering applications such as communication systems, networking, and digital signal processing.
