Description and Introduction

CMOS SyncFIFOO 64 X 9, 256 x 9, 512 x 9, 1024 X 9, 2048 X 9 and 4096 x 9 The IDT72421L15PF is a high-speed, low-power FIFO (First-In, First-Out) memory device manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Part Number:** IDT72421L15PF  
- **Type:** Synchronous FIFO  
- **Organization:** 512 x 9 bits  
- **Speed:** 15 ns access time  
- **Operating Voltage:** 5V  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 28-lead Plastic Flatpack (PF)  

### **Descriptions:**
- Designed for high-speed data buffering applications.  
- Supports synchronous read and write operations.  
- Features automatic flag generation for empty, full, and half-full conditions.  
- Low power consumption for energy-efficient operation.  

### **Features:**
- **High-Speed Operation:** 15 ns access time for fast data transfers.  
- **Synchronous Interface:** Clock-controlled read and write operations.  
- **Flag Controls:** Programmable Almost-Full/Almost-Empty flags.  
- **Expandable Depth:** Can be cascaded for deeper FIFO configurations.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Low Standby Power:** Reduces power consumption when idle.  

This device is commonly used in telecommunications, networking, and data processing systems where high-speed buffering is required.

Alternative Part Number

  • CY7C421-15PC --: Pin-compatible FIFO memory in the same 15 ns speed grade and DIP package, widely used as a direct second-source for the 72421 family.
  • SN74ACT7803-15P --: Comparable asynchronous FIFO with matching 15 ns access time and similar organization, suitable functional drop-in with minor timing review.
  • IDT7203L15P --: Same vendor FIFO family with equivalent 15 ns speed and pinout, offering a low-risk replacement from the original manufacturer's line.
