JM54AC14BCA-RH

Inverter Gates Overview

The JM54AC14BCA-RH is a hex Schmitt inverter belonging to the 54AC series of high-speed CMOS logic functions. It is specifically engineered to meet rigorous radiation requirements for aerospace applications, offering high total ionizing dose (TID) hardness, single event latch-up immunity, and characterized single event upset performance. The device operates within a voltage range of 2 V to 6 V and supports an extended temperature range from -55 °C to +125 °C. Housed in hermetic ceramic packages and qualified under QML-V standards, it is designed for reliability in demanding space conditions.

Inverter Gates Feature Summary

• High radiation hardness including TID resistance up to 300 krad(Si) RHA
• Immunity to single event latch-up up to 110 MeV.cm²/mg
• Characterized for single event upset and single event transient effects
• Hermetic ceramic packaging with QML-V qualification

Inverter Gates Applications

• Aerospace systems requiring radiation-hardened logic
• Harsh environmental electronic circuits
• Spacecraft bus interfaces and address drivers

Inverter Gates Procurement Notes

Verify that the specific part number includes the 'JM' prefix and 'RH' suffix to confirm military-grade radiation hardening and hermetic sealing. Ensure procurement sources provide QML-V certification documentation. Confirm the package type matches the required hermetic ceramic specification for the intended application environment.

Inverter Gates Selection Notes

Select this component when standard commercial logic fails to meet radiation tolerance requirements. It is suitable for designs needing Schmitt trigger inputs to ensure clean signal transitions in noisy environments. Verify that the 2 V to 6 V operating voltage aligns with the system power supply constraints.

Inverter Gates Part Context

This component is part of the broader 54AC/54ACT family of high-speed CMOS logic functions. Unlike standard commercial variants, the JM54AC14BCA-RH variant is fabricated and tested to meet strict military and aerospace standards. It provides hex inverter functionality with Schmitt triggers, ensuring robust noise immunity in critical digital systems.

Inverter Gates Replacement Considerations

Direct replacements must also be QML-V qualified radiation-hardened devices. Verify pin compatibility and electrical specifications against other 54AC series parts. Standard commercial AC14 equivalents are not suitable substitutes due to lack of radiation hardness.
