Description and Introduction

512 × 36 CLOCKED FIRST-IN, FIRST-OUT MEMORY The SN74ACT3631-30PQ is a 512 × 36 synchronous FIFO memory device manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Memory Size:** 512 × 36 bits  
- **Operating Voltage:** 4.5V to 5.5V  
- **Speed:** 30 ns access time  
- **Package:** 120-pin plastic quad flat pack (PQ)  
- **I/O Type:** 5V TTL-compatible  
- **Operating Temperature Range:** -40°C to 85°C  

### **Features:**  
- **Synchronous FIFO operation** with independent read and write clocks  
- **Programmable Almost Full/Almost Empty flags** for flow control  
- **Retransmit capability** for data recovery  
- **Bidirectional data bus** for flexible interfacing  
- **Low-power CMOS technology**  
- **Expandable depth and width** for larger memory configurations  

This device is designed for high-speed data buffering in applications such as networking, telecommunications, and data acquisition systems.

Application Scenarios & Design Considerations

512 × 36 CLOCKED FIRST-IN, FIRST-OUT MEMORY

Alternative Part Number

  • CY7C433-30JC --: Pin-compatible FIFO memory with similar 30 ns speed grade and 4K x 18 organization, widely used as a drop-in alternative to TI ACT3631 FIFOs.
  • IDT7205L30J --: IDT 7205 series asynchronous FIFO offers comparable depth and 30 ns access time, suitable functional replacement with different naming series.
  • SN74ACT7808-30PQ --: Same TI ACT family FIFO with similar architecture and 30 ns speed, different base part number so it is distinguishable from the source.
