72104L35J

Overview

The Renesas Electronics Corporation 72104L35J is an asynchronous FIFO memory device with a capacity of 4K x 9 bits. It operates at a data rate of 22.2 MHz and features a 35 ns access time. The component supports unidirectional data flow and is housed in a 44-PLCC package measuring 16.59x16.59 mm. Maximum supply current is 140 mA.

Feature Summary

• Asynchronous operation for flexible clock domain interfacing
• Unidirectional data transfer capability
• Surface mount PLCC packaging

Applications

• Buffering data between asynchronous logic domains
• Interface bridging in embedded systems
• Data storage in high-speed digital circuits

Procurement Notes

Verify RoHS compliance status as sources indicate conflicting information. Confirm package integrity upon receipt due to potential handling sensitivity. Check datasheet for specific moisture sensitivity level requirements before soldering. Ensure supplier documentation matches the exact part number suffix.

Selection Notes

Select this component when a 4K x 9 asynchronous buffer is required. Compare against similar models like 72V04L35J for voltage compatibility. Verify that the 35 ns speed meets system timing constraints. Consider the 44-pin PLCC footprint for PCB layout planning.

Part Context

Part of the Renesas 72104 series, designed for general-purpose FIFO applications. Related parts include 72V04L35J and IDT72104 variants. The series offers various access times and organization options for different memory buffering needs.

Replacement Considerations

IDT72104L35J is a direct equivalent from Integrated Device Technology. Verify pinout compatibility before substitution. Check if alternative packages are available for existing designs.
