27LS07DM/B

Overview

The 27LS07DM/B is a standard SRAM IC manufactured by Rochester Electronics, LLC. It features a memory organization of 16 words by 4 bits (16x4). The device operates within a specified voltage range and is designed for low-power applications. It utilizes a CMOS technology process to ensure efficient performance in embedded systems requiring reliable data storage capabilities.

Feature Summary

• Standard SRAM architecture providing non-volatile-like retention during power cycles when supported by backup circuits
• Low-power consumption characteristics suitable for battery-operated or energy-efficient designs
• CMOS technology implementation ensuring compatibility with standard logic families

Applications

• Serial-to-parallel conversion buffers in communication interfaces
• Parallel-to-serial data buffering for transmission systems
• General-purpose temporary data storage in microcontroller-based systems

Procurement Notes

Verify the specific lot date code and manufacturing origin upon receipt, as Rochester Electronics sources components from various authorized foundries. Confirm that the package lead finish matches your assembly requirements. Ensure proper electrostatic discharge handling procedures are followed during installation to prevent damage to the sensitive CMOS input structures.

Selection Notes

Select this component when a small, low-power static RAM buffer is required for serial data processing tasks. Consider the 16x4 word size limitation against your system's data width needs. Evaluate the operating temperature range to ensure it meets your environmental specifications. Verify interface compatibility with your existing logic levels before integration into the design.

Part Context

Rochester Electronics specializes in sustaining production of legacy and obsolete semiconductor products. This part belongs to their portfolio of maintained memory devices, ensuring availability for long-term industrial and commercial applications where original manufacturers may have discontinued support. It represents a solution for maintaining product lifecycles without redesigning around newer technologies.

Replacement Considerations

Direct substitutes include other 16x4 SRAM variants from different manufacturers such as Intel or AMD, provided pinouts and electrical characteristics match. Verify functional equivalence regarding access times and power consumption. Cross-reference with NXP or Philips legacy parts if the design originated from those ecosystems.
