6116LA45DB

Overview

The IDT6116LA45DB is a 16K-bit (2K x 8) asynchronous static random-access memory (SRAM) manufactured by Integrated Device Technology. It operates within a supply voltage range of 4.5V to 5.5V and features a maximum access time of 45ns. The device utilizes a parallel interface and is housed in a 24-pin ceramic dual in-line package (CDIP). It supports an industrial temperature range from -55°C to +125°C, ensuring reliable performance in demanding environments.

Feature Summary

• Asynchronous parallel SRAM architecture for standard data storage applications
• High-temperature operation capability suitable for industrial and military specifications
• CMOS technology providing low power consumption characteristics

Applications

• Industrial control systems requiring wide temperature tolerance
• Military-grade electronic equipment and avionics
• Embedded memory solutions in harsh environment computing devices

Procurement Notes

Verify component authenticity due to potential availability of refurbished or obsolete stock. Confirm RoHS compliance status as older batches may not meet current environmental directives. Check for specific packaging variations such as lead-free terminations if required by assembly processes. Ensure the ceramic package integrity matches design specifications for thermal and mechanical stability.

Selection Notes

Select this component when high-temperature reliability and CMOS efficiency are prioritized over cost. Compare with plastic DIP variants if extreme thermal conditions are not present. Consider pin compatibility with existing PCB footprints designed for 24-pin CDIP packages. Evaluate system power budgets against typical standby and active currents specified in the datasheet.

Part Context

This part belongs to the IDT6116 family of 16Kb SRAMs, which offers various speed grades and package options. The LA suffix typically denotes military/industrial temperature ranges and ceramic packaging. It serves as a legacy solution for systems requiring non-volatile-like retention during power cycles or specialized industrial interfaces where robustness is critical.

Replacement Considerations

Direct substitutes include IDT6116LA45EB and IDT6116LA45FB, which share similar electrical characteristics and pinouts. Verify package dimensions and terminal configurations before substitution to ensure mechanical fit.
