54LS356J

Overview

The 54LS356J is an 8-to-1 data selector and multiplexer manufactured by Rochester Electronics, LLC. It belongs to the LS series of low-power Schottky TTL logic devices. The component features a dual marking designation of M38510/10502BEA, indicating compliance with military standards. It provides eight data inputs, three address select lines, and a single output. The device is housed in a CDIP14 ceramic dual in-line package with glass-sealed construction, suitable for high-reliability applications requiring robust physical packaging.

Feature Summary

• Provides 8-to-1 data selection capability for digital signal routing
• Utilizes low-power Schottky (LS) TTL technology for efficient operation
• Constructed in a hermetically sealed ceramic DIP package for environmental protection

Applications

• Data selection circuits
• Bus multiplexing systems
• Digital logic routing

Procurement Notes

Verify the specific suffix or dual-marking code (e.g., M38510/10502BEA) against procurement requirements, as Rochester Electronics components often carry manufacturer-specific identifiers. Confirm that the ceramic DIP-14 package matches the mechanical constraints of the target assembly. Ensure the LS series performance characteristics align with the system's power and speed specifications before finalizing the order.

Selection Notes

Select this component when an 8-channel multiplexer is required within a low-power Schottky TTL design environment. The ceramic package makes it appropriate for harsh environments where plastic packages may fail. Consider the propagation delay and power consumption typical of the LS series relative to other logic families if higher speed or lower voltage operation is needed.

Part Context

Rochester Electronics specializes in supplying critical semiconductors, including legacy and obsolete parts, often sourced from original manufacturer wafers. The 54LS356J falls under their Logic category, specifically within Signal Switches and Multiplexers. These products are guaranteed to meet original OEM specifications, serving industries such as aerospace and defense that require long-term availability and reliability.

Replacement Considerations

Check for direct equivalents in the SN54LS151 or SN74LS151 families, which share similar 8-to-1 multiplexer functionality. Verify pin compatibility and electrical parameters, particularly input/output voltage levels and drive capabilities, to ensure seamless integration without circuit redesign.
