7164L35TPG

Memory IC Overview

The Renesas Electronics Corporation 7164L35TPG is a high-speed CMOS static random-access memory (SRAM) organized as 64K bits (8K x 8). It features a parallel interface with a maximum access time of 35 ns. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports through-hole installation in a 28-pin dual in-line package (PDIP, 0.300 inch width). It functions reliably across an ambient temperature range of 0°C to 70°C.

Memory IC Feature Summary

• High-speed asynchronous SRAM technology for rapid data access
• Parallel interface architecture supporting standard digital logic levels
• Volatile memory storage maintaining data integrity during power supply

Memory IC Applications

• Industrial control systems requiring fast local data buffering
• Embedded applications utilizing 5V logic families
• Legacy hardware maintenance and replacement scenarios

Memory IC Procurement Notes

Verify component authenticity due to end-of-life status. Confirm package dimensions match 28-PDIP specifications. Ensure supply voltage requirements align with system design. Check for RoHS compliance documentation if required by project standards. Validate lead times as availability may be limited.

Memory IC Selection Notes

Select this component when a 64K-bit parallel SRAM with 35 ns access speed is required. It suits designs operating at 5V with through-hole mounting constraints. Consider alternatives only if faster access times or lower voltage operation are necessary. Verify compatibility with existing PCB footprints and logic interfaces.

Memory IC Part Context

This part belongs to the IDT/Renesas 7164 series of high-speed CMOS SRAMs. It shares architectural similarities with variants like the 7164S25TPG and 7164L20TPG, differing primarily in access speed and suffix codes. The series is designed for general-purpose memory applications in industrial and commercial electronics.

Memory IC Replacement Considerations

Direct substitutes include other 7164L series variants with compatible pinouts. Verify electrical parameters such as access time and voltage ranges before substitution. Cross-reference with manufacturer obsolescence notices for long-term availability.
