54ACT157JRQMLV

Overview

The 54ACT157JRQMLV is a radiation-hardened quad 2-channel multiplexer belonging to the high-speed CMOS 54ACTxxxx series. Designed for aerospace applications, it features hermetic ceramic packaging and QML-V qualification. The device operates within a voltage range of 4.5 V to 5.5 V and withstands total ionizing doses up to 300 krad (Si). It exhibits immunity to single-event latch-up up to 110 MeV.cm²/mg and functions reliably across a temperature range of -55 °C to +125 °C.

Feature Summary

• Radiation hardness with immunity to single-event latch-up and upset
• Hermetic ceramic package construction for harsh environments
• Qualified under QML-V standards for aerospace reliability

Applications

• Aerospace signal routing systems
• Harsh environment data acquisition
• Spacecraft bus interface circuits

Procurement Notes

Verify that the component carries valid QML-V certification marks and matches the specific SMD specification drawing available on the DLA website. Confirm the presence of hermetic sealing integrity and radiation test reports corresponding to the 54ACT157 part number before acceptance.

Selection Notes

Select this component when radiation tolerance and hermetic sealing are mandatory requirements. Ensure the system voltage aligns with the 4.5 V to 5.5 V operating range specified for the ACT series. Consider the thermal management capabilities required for the -55 °C to +125 °C operational envelope in your design.

Part Context

This part belongs to the 54AC/54ACT family of radiation-hardened CMOS logic functions. These components are engineered to meet stringent aerospace industry standards, offering high-speed performance alongside robust protection against space radiation effects.
