JM54AC161S2A-RH

Counter Dividers Overview

The JM54AC161S2A-RH is a radiation-hardened synchronous binary counter manufactured by National Semiconductor. It belongs to the 54AC series, which utilizes high-speed CMOS technology designed for aerospace and harsh environmental applications. The device features an asynchronous clear function and operates within a voltage range of 2 V to 6 V. It is housed in a ceramic hermetic package to ensure reliability under extreme conditions.

Counter Dividers Feature Summary

• High radiation hardness against total ionizing dose and single event effects
• Hermetic ceramic packaging for harsh environment durability
• Synchronous binary counting with asynchronous clear functionality

Counter Dividers Applications

• Aerospace systems requiring radiation tolerance
• Harsh environmental electronic circuits
• Military grade digital logic applications

Counter Dividers Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor was acquired by Texas Instruments. Confirm that the specific suffix indicates the radiation-hardened variant and hermetic ceramic package. Ensure compatibility with MIL-STD requirements if applicable to your system design.

Counter Dividers Selection Notes

Select this component when radiation hardness is mandatory for the application environment. The 54AC series offers higher speed than standard 54HC counterparts while maintaining low power consumption. Verify that the operating voltage range aligns with the system's power supply specifications.

Counter Dividers Part Context

This part is part of the 54ACxxxx family, specifically engineered for space and defense industries. It provides robust performance in environments where standard commercial components would fail due to radiation exposure or temperature extremes.

Counter Dividers Replacement Considerations

Check for direct equivalents from other manufacturers offering QML-V qualified radiation-hardened counters. Ensure pinout and electrical characteristics match exactly before substitution.
