72125L25SOG

Overview

The Renesas 72125L25SOG is an asynchronous FIFO memory device with a capacity of 16K words (1K x 16 bits). It features a 25 ns access time and supports data rates up to 50 MHz. The component operates on a single 4.5 V to 5.5 V supply voltage and is housed in a 28-pin SOIC package.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Uni-directional data flow architecture
• Wide 16-bit word width buffering capability

Applications

• Laser printer interface buffering
• FAX machine data handling
• Local area network (LAN) communication systems
• Video storage applications

Procurement Notes

Verify current availability status as the component may be subject to discontinuation notices. Confirm RoHS compliance requirements, as specific variants may not meet current environmental standards. Ensure the 28-SOIC package footprint matches the target PCB design before finalizing procurement orders.

Selection Notes

Select this part when wide 16-bit word buffering is required between asynchronous systems. The 25 ns speed grade suits moderate-speed data transfer needs. Consider the uni-directional nature of the buffer when designing system data paths.

Part Context

This component belongs to the 72125 series of asynchronous FIFOs manufactured by Renesas Electronics. It provides dedicated memory buffering solutions for digital signal processing and data acquisition systems requiring temporary storage between mismatched data rates.

Replacement Considerations

Check for IDT72125L25SO as a potential equivalent part number from the same manufacturer lineage. Verify pin compatibility and electrical specifications against any alternative sources before substitution.
