SN74ALVC3651-15PCB

Overview

The SN74ALVC3651-15PCB is a synchronous bi-directional FIFO memory integrated circuit manufactured by Texas Instruments. It features an organization of 2K x 36 bits, providing a total capacity of 72 kilobits. The device operates at a maximum frequency of 66.7 MHz with a propagation delay of 9.5 ns. It is housed in a 120-pin HLQFP package and is characterized for operation within the commercial temperature range of 0°C to 70°C.

Feature Summary

• Bi-directional data transfer capability between Port A and Port B
• Synchronous FIFO architecture with retransmit capability for previously read data access
• CMOS technology implementation for low power consumption

Applications

• Data buffering in high-speed digital systems
• Interface bridging between components operating at different clock domains
• Temporary storage in communication protocols requiring flow control

Procurement Notes

Verify the specific suffix '15PCB' against the official Texas Instruments datasheet to confirm pinout compatibility and electrical characteristics. Ensure the HLQFP-120 package matches your PCB footprint requirements. Confirm that the 0°C to 70°C operating range meets your environmental specifications before procurement.

Selection Notes

Select this component when a synchronous, bi-directional FIFO with 36-bit word width is required. The 66.7 MHz speed rating suits moderate-to-high throughput applications. Consider the 120-pin package size relative to available board space. Verify voltage levels align with system logic standards.

Part Context

This part belongs to the SN74ALVC3651 family of synchronous FIFOs from Texas Instruments. The family offers various speed grades and package options. The ALVC series utilizes advanced low-voltage CMOS technology, distinguishing it from older ACT or LVC variants in terms of power efficiency and switching speeds.

Replacement Considerations

Check for SN74ALVC3651 variants with different speed grades (e.g., -10, -20) if timing constraints differ. Verify package compatibility if substituting with other manufacturers offering equivalent 2Kx36 synchronous FIFOs in HLQFP-120.
