72401L25PDG

FIFOs Memory Overview

The Renesas Electronics Corporation 72401L25PDG is an asynchronous 64 x 4 First-In, First-Out (FIFO) memory device. It operates with a maximum shift rate of 45MHz and supports low fall-through time for efficient data buffering between digital machines with varying operating frequencies. The component features high data output drive capability and is fully expandable by both bit width and word depth. It is housed in a 16-pin plastic DIP package and is designed for industrial temperature ranges from -40°C to +85°C.

FIFOs Memory Feature Summary

• Asynchronous read and write operations allow buffering between digital systems with widely varying clock frequencies.
• High-speed performance with a maximum shift rate of 45MHz suitable for communication applications.
• Fully expandable architecture supporting expansion by both bit width and word depth.

FIFOs Memory Applications

• High-speed communication systems
• Controller applications requiring data buffering
• Interfacing digital machines with differing operating frequencies

FIFOs Memory Procurement Notes

Verify the specific suffix 'PDG' against official Renesas documentation to confirm package type and lead-free status. Cross-reference with the standard 72401 family datasheet for pinout compatibility. Confirm availability as this series may be subject to discontinuation notices. Ensure the supplier provides valid traceability documents for industrial grade components.

FIFOs Memory Selection Notes

Select this component when asynchronous buffering is required between systems with mismatched clock speeds. The 64x4 organization suits narrow data paths. Verify that the 45MHz speed meets system timing requirements. Consider the 16-pin DIP package constraints for PCB layout. Check if the industrial temperature range aligns with the operational environment.

FIFOs Memory Part Context

The 72401 belongs to the IDT/Renesas 72400 series of asynchronous FIFO memories. This family is known for providing reliable data buffering solutions in legacy and industrial systems. The 72401 specifically offers a 64-word by 4-bit configuration, distinguishing it from wider or deeper variants in the same product line.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible substitutes within the 72401 series, such as the 72401L35 or 72401L45 for higher speed options. Verify if newer asynchronous FIFO families from Renesas offer equivalent functionality with improved power consumption or packaging options.
