72125L25TPG

Overview

The Renesas 72125L25TPG is an asynchronous FIFO memory IC with a storage capacity of 16K bits, organized as 1K x 16. It features a parallel interface and supports a maximum access time of 25 ns. The device operates within a supply voltage range of 4.5 V to 5.5 V. It is housed in a 28-pin plastic dual in-line package (PDIP) designed for through-hole mounting.

Feature Summary

• Asynchronous operation allows independent read and write clock domains
• Parallel-to-serial architecture buffers wide word widths
• Supports unidirectional data flow for buffering applications

Applications

• Laser printer data buffering
• FAX machine signal processing
• Local area network (LAN) interface buffering
• Video storage systems
• Disk drive controller interfaces

Procurement Notes

Verify component authenticity due to end-of-life status. Confirm package integrity and pin alignment against the 28-pin PDIP specification. Validate datasheet revisions to ensure compatibility with existing system timing requirements before integration into new designs.

Selection Notes

Select this component when asynchronous buffering of 16-bit data streams is required. Ensure the design accommodates the 4.5 V to 5.5 V operating range. Consider the 25 ns access time for throughput requirements. Verify that the through-hole packaging aligns with the PCB layout constraints.

Part Context

This part belongs to the Renesas 72125 series of asynchronous FIFOs. It provides a solution for decoupling data transfer rates between different system components. The 1K x 16 organization offers moderate depth for intermediate data storage in high-speed digital interfaces.

Replacement Considerations

Check for direct cross-reference part numbers from IDT or Renesas legacy portfolios. Verify pinout compatibility and electrical specifications if substituting with other asynchronous FIFOs. Confirm availability as the original part is scheduled for discontinuation.
