54F381ADM/B

Overview

The 54F381ADM/B is a 4-bit arithmetic logic unit (ALU) and function generator manufactured by Rochester Electronics, LLC. It belongs to the SN54/74F series of high-speed Schottky logic devices. The component performs various arithmetic and logical operations based on mode select inputs. It features standard TTL-compatible logic levels and is designed for applications requiring fast data processing in digital systems.

Feature Summary

• Performs multiple arithmetic and logical functions via mode selection
• High-speed operation characteristic of Schottky logic family
• Standard TTL voltage level compatibility

Applications

• Digital arithmetic processing units
• Logic function generation circuits
• Data path control systems

Procurement Notes

Verify the manufacturer origin as Rochester Electronics, LLC, which may supply remanufactured or surplus components rather than original factory new stock. Confirm the package type matches the ADM suffix specification. Check for RoHS compliance status if required by your assembly process, as legacy F-series parts may not meet current environmental standards. Ensure the part number exactly matches 54F381ADM/B to avoid confusion with similar ALU variants.

Selection Notes

Select this component when a 4-bit ALU with Schottky speed is required in a design utilizing the 54F series logic family. It serves as a direct replacement for original SN54F381 devices in military or aerospace specifications where Rochester Electronics qualified sources are permitted. Consider pinout compatibility and voltage requirements against existing system constraints before integration.

Part Context

Rochester Electronics specializes in providing lifecycle support for obsolete and hard-to-find integrated circuits. They source die from original manufacturers or recreate them using original intellectual property. This specific ALU is part of their specialty logic portfolio, offering continuity for designs that cannot migrate to newer technology nodes.

Replacement Considerations

Direct functional equivalents include the SN54F381 and SN74F381. Verify pin compatibility and electrical characteristics against the original design specifications when substituting.
