54LS259B/BEA

Overview

The 54LS259B/BEA is a military-grade 8-bit addressable latch manufactured by Rochester Electronics. It belongs to the LS series of TTL logic devices, featuring low-power Schottky technology for enhanced speed and reduced power consumption. The component operates within an extended temperature range from -55 °C to 125 °C, ensuring reliability in harsh environments. It utilizes a ceramic DIP-16 package with metal-sealed cofired construction, providing robust physical protection. The device includes a propagation delay of 24 ns and supports true output polarity.

Feature Summary

Military-grade construction with ceramic DIP-16 packaging for durability
Low-power Schottky (LS) TTL technology for efficient operation
Extended temperature range capability suitable for extreme conditions
Dual-marked designation indicating compliance with specific military standards

Applications

Military aerospace electronic systems requiring high reliability
Industrial control applications operating in extreme temperatures
Defense communication equipment needing stable latch functionality
Harsh environment data acquisition systems

Procurement Notes

Verify the dual marking M38510/31605BEA on the component surface to confirm authenticity and specific military grade classification. Ensure the supplier provides traceability documentation consistent with Rochester Electronics' authorized distribution channels. Confirm that the ceramic package integrity meets MIL-STD requirements for your specific environmental application before final integration.

Selection Notes

Select this component when military-grade reliability and extended temperature performance are critical. The LS series offers a balance of speed and power efficiency suitable for complex digital logic circuits. Consider the ceramic DIP-16 package if hermetic sealing or mechanical robustness is required over standard plastic packages. Verify compatibility with existing TTL logic levels in your system design.

Part Context

Rochester Electronics specializes in sustaining obsolete and hard-to-find semiconductor products. This part is a continuation of legacy Texas Instruments SN54LS259 designs, maintained for long-term supply chain stability.
