IDT6116SA45TPI

Memory IC Overview

The IDT6116SA45TPI is a 16K-bit (2K x 8) asynchronous static RAM manufactured by Renesas Electronics Corporation. It features a parallel interface with a maximum access time of 45 ns and operates on a 4.5V to 5.5V supply voltage. The component utilizes CMOS technology for low-power consumption and includes a reduced power standby mode. It is housed in a 24-pin Plastic Dual In-Line Package (PDIP) designed for through-hole mounting.

Memory IC Feature Summary

• CMOS technology virtually eliminates alpha particle soft-error rates
• Fully static asynchronous circuitry requiring no clocks or refreshing
• Reduced power standby mode activated when chip select goes HIGH
• Inputs and outputs are directly TTL-compatible

Memory IC Applications

• Military temperature applications demanding high performance and reliability
• Industrial systems requiring non-volatile data retention via battery backup
• General-purpose memory storage in embedded control systems

Memory IC Procurement Notes

Verify the specific suffix 'TP' against official documentation, as standard datasheets list 'P' for 300 mil plastic DIP and 'TD' for ceramic options. Confirm RoHS compliance status, as historical IDT versions often lack it. Check current lifecycle status, as this series may be discontinued or subject to product change notices. Ensure the package pitch matches the target PCB footprint.

Memory IC Selection Notes

Select this component for designs requiring robust MIL-STD-833 Class B reliability or standard industrial commercial grade operation. Consider the LA variant if battery backup data retention at 2V is required. Verify that the 45 ns speed meets system timing constraints. Ensure the 24-pin DIP form factor aligns with assembly capabilities and board space requirements.

Memory IC Part Context

This device belongs to the IDT6116 family of 16K-bit CMOS SRAMs. The family offers various access speeds ranging from 15 ns to 150 ns and multiple packaging options including DIP, SOIC, and SOJ. The SA designation indicates standard power consumption, while the LA version supports low-power battery backup operations.

Memory IC Replacement Considerations

Compatible substitutes include other 16Kx8 asynchronous SRAMs with similar 45 ns access times and 5V logic levels. Verify pinout compatibility and electrical characteristics before integration.
