Description and Introduction

CMOS SUPERSYNC FIFOO 16,384 x 9, 32,768 x 9 The IDT72261L20TF is a high-speed, low-power, first-in first-out (FIFO) memory device manufactured by IDT (Integrated Device Technology). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Part Number:** IDT72261L20TF  
- **Type:** Synchronous FIFO  
- **Organization:** 512 x 18  
- **Speed:** 20 ns access time  
- **Operating Voltage:** 5V  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **Package:** 64-pin Thin Quad Flat Pack (TQFP)  
- **I/O Type:** 5V TTL-compatible  

### **Descriptions:**
- The IDT72261L20TF is a high-performance FIFO memory designed for buffering data in applications requiring high-speed data transfer.  
- It supports synchronous operation with separate read and write clocks.  
- Features programmable flags (Almost Full, Almost Empty, Full, Empty) for efficient data flow control.  
- Suitable for networking, telecommunications, and data acquisition systems.  

### **Features:**
- **High-Speed Operation:** 20 ns access time.  
- **Low Power Consumption:** Optimized for power-sensitive applications.  
- **Programmable Flags:** Includes Full, Empty, Almost Full, and Almost Empty flags.  
- **Retransmit Function:** Allows re-reading of data without external logic.  
- **Expandable Depth and Width:** Can be cascaded for larger FIFO configurations.  
- **TTL-Compatible Inputs/Outputs:** Ensures easy interfacing with standard logic devices.  
- **Bidirectional Data Flow:** Supports unidirectional or bidirectional data transfer.  

This FIFO is commonly used in high-speed data buffering, communication interfaces, and digital signal processing applications.

Application Scenarios & Design Considerations

CMOS SUPERSYNC FIFOO 16,384 x 9, 32,768 x 9

Alternative Part Number

  • CY7C4261V-20JC --: Pin-compatible synchronous FIFO with similar 16K x 9 density and 20 ns speed grade, widely used as a drop-in replacement for IDT72261 series.
  • SN74ACT7803-20FN --: Comparable 512 x 18 synchronous FIFO from TI's ACT family, offering similar timing and interface characteristics for buffering applications.
  • 72V261L20PF --: Renesas (formerly IDT-compatible line) 16K x 9 synchronous FIFO with 20 ns access time, functionally equivalent and available from an alternate supplier.
  • CY7C4261V-20ASC --: Pin-compatible synchronous FIFO with similar 16K x 9 density and 20 ns speed grade, widely available as a drop-in functional replacement.
  • SN74ACT7803-20DL --: Synchronous FIFO in the same density class with 20 ns access time, suitable for buffering applications where the IDT part is used.
