7204L30TDB

Overview

The Renesas Electronics Corporation 7204L30TDB is an asynchronous FIFO memory device with a storage capacity of 36k bits, organized as 4K x 9. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 30 ns. The component supports a data rate of 25 MHz and draws a maximum supply current of 150 mA. It is housed in a 28-CDIP package (0.300 inch, 7.62 mm) designed for through-hole mounting.

Feature Summary

• Supports first-in/first-out data loading and emptying using Full and Empty flags to prevent data loss.

Applications

• Asynchronous data buffering between different clock domains
• Interface bridging in digital logic systems

Procurement Notes

Verify the specific suffix TDB confirms the 28-CDIP package and unidirectional bus configuration. Confirm RoHS compliance status and check for End-of-Life notifications, as discontinuance notices may apply to this series. Ensure the supplier provides valid traceability documentation for the manufacturer part number.

Selection Notes

Select this component when a 4K x 9 asynchronous FIFO with 30 ns access time is required. The 28-CDIP package is suitable for through-hole applications requiring robust mechanical stability. Verify that the 25 MHz data rate meets system timing requirements and that the 150 mA current consumption fits power budgets.

Part Context

This device belongs to the 7204L series of dual-port FIFO memories. It utilizes CMOS technology to provide reliable data storage and retrieval. The 7204L30TDB variant specifically denotes the 30 ns speed grade and CDIP packaging within the broader family of asynchronous memory solutions.

Replacement Considerations

Cross-reference with IDT7204L30TDB for potential pin-compatible alternatives. Verify functional equivalence regarding bus directionality and access times before substitution.
