Overview
The 27LS00AFM/B is a Static RAM component manufactured by Rochester Electronics, LLC. It features a memory organization of 256 x 1 bits. The device utilizes Metal-Oxide Semiconductor (FET) technology and operates within the Ultra High Frequency band. It is housed in a TO-272BA package with six pins. Key electrical specifications include a minimum drain-source breakdown voltage of 40 V and a maximum drain current of 6 A. The component is RoHS compliant and classified as a single configuration device.
Feature Summary
- Provides static random access memory functionality using metal-oxide semiconductor technology
- Designed for operation in the ultra high frequency band
- Constructed in a six-pin plastic TO-272BA package
Applications
- Asynchronous memory storage systems
- Embedded data retention applications
- Legacy electronic system maintenance
Procurement Notes
Verify the specific lot code and date code upon receipt to ensure authenticity. Rochester Electronics products are sourced from original manufacturers or authorized channels. Confirm that the physical marking matches the part number exactly. Request test reports if performance validation against original OEM specifications is required for critical integration.
Selection Notes
Select this component when a 256 x 1 bit SRAM configuration is required for UHF applications. Ensure the design accommodates the TO-272BA surface mount package. Verify that the 40 V breakdown voltage and 6 A current limits align with the circuit requirements. Consider the TTL compatibility implied by the LS designation for logic interfacing.
Part Context
Rochester Electronics specializes in sustaining obsolete and hard-to-find semiconductor products. This company maintains production of licensed devices that are no longer actively marketed by original OEMs. The 27LS00AFM/B represents their capability to provide verified replacements for legacy memory components used in long-life industrial and military equipment.
Replacement Considerations
Cross-reference with other 256x1 SRAM variants in the TO-272BA package. Verify pinout compatibility before substitution. Check if alternative suppliers offer equivalent speed grades and voltage tolerances.
