Description and Introduction

CMOS ASYNCHRONOUS FIFO 2048 x 9, 4096 x 9, 8192 x 9 and 16384 x 9 The IDT7205 is a high-speed, low-power 16K x 9-bit asynchronous FIFO (First-In, First-Out) memory manufactured by Integrated Device Technology (IDT).  

### **Specifications:**  
- **Memory Organization:** 16,384 words x 9 bits  
- **Operating Voltage:** 5V ±10%  
- **Access Time:** 25 ns (max)  
- **Cycle Time:** 35 ns (max)  
- **Power Consumption:**  
  - Active: 650 mW (typical)  
  - Standby: 35 mW (typical)  
- **Operating Temperature Range:**  
  - Commercial: 0°C to +70°C  
  - Industrial: -40°C to +85°C  
- **Package Options:** 28-pin DIP, PLCC, and SOIC  

### **Descriptions and Features:**  
- **Asynchronous Operation:** No clock required for read/write operations.  
- **Full and Empty Flags:** Indicates FIFO status (full, empty, or partial).  
- **Expandable Depth:** Can be cascaded for deeper FIFO configurations.  
- **Bidirectional Data Flow:** Supports independent read and write operations.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **High-Speed Performance:** Suitable for buffering in high-speed data transfer applications.  
- **Low-Power CMOS Technology:** Reduces power consumption in active and standby modes.  

The IDT7205 is commonly used in data buffering, communication systems, and digital signal processing applications.

Application Scenarios & Design Considerations

CMOS ASYNCHRONOUS FIFO 2048 x 9, 4096 x 9, 8192 x 9 and 16384 x 9

Alternative Part Number

  • CY7C4255-15PC --: Cypress FIFO memory in the same 4K x 9 asynchronous FIFO class as the IDT7205, pin-compatible in many designs and widely available.
  • SN74ACT7805-20PN --: TI asynchronous FIFO with comparable depth and width, suitable drop-in replacement for buffering applications using the IDT7205.
  • CY7C4215-15PC --: Smaller-density Cypress FIFO from the same family, usable when the full 4K depth of the IDT7205 is not required.
