JM54AC157SEA-RH

Overview

The JM54AC157SEA-RH is a rad-hard quad 2-channel multiplexer from the 54ACxxxx series, designed for aerospace radiation requirements. It features high-speed CMOS technology with immunity to single event latch-up (SEL) and single event upset (SEU). The device operates within a voltage range of 2 V to 6 V and withstands total ionizing doses up to 300 krad (Si). It is housed in hermetic packages suitable for extreme environmental conditions, ranging from -55 °C to +125 °C.

Feature Summary

• Radiation hardness qualification including SEL immunity up to 110 MeV.cm²/mg
• Hermetic packaging for difficult environmental conditions
• High-speed CMOS logic function design

Applications

• Aerospace industry circuits requiring radiation tolerance
• Systems demanding immunity to single event effects
• Military microcircuit applications under SMD specifications

Procurement Notes

Verify that the specific part number matches the manufacturer's official documentation for the 54AC157 series. Confirm compliance with SMD specifications available on the DLA website. Ensure the hermetic package type aligns with project environmental requirements. Validate radiation hardness ratings against mission-specific thresholds before procurement.

Selection Notes

Select this component when radiation hardness and hermetic sealing are mandatory. The 54AC series offers high-speed performance suitable for complex logic functions. Verify operating voltage compatibility within the 2 V to 6 V range. Consider the temperature range of -55 °C to +125 °C for harsh environment suitability.

Part Context

This component belongs to the 54ACxxxx and 54ACTxxxx series of high-speed CMOS functions. These series are specifically engineered to meet stringent radiation requirements for the aerospace sector. The family includes various gates, flip-flops, counters, and bus interfaces, all characterized by robust radiation tolerance and hermetic construction options.

Replacement Considerations

Check for other parts within the 54ACxxxx series that share identical radiation qualifications and hermetic packaging. Verify functional equivalence for quad 2-channel multiplexing operations. Ensure substitute components meet the same SEL and SEU immunity standards.
