JM54AC541S2A-RH

Overview

The JM54AC541S2A-RH is a high-speed CMOS octal buffer and driver manufactured by National Semiconductor, now part of Texas Instruments. It features true outputs with three-state capability and dual output enables for flexible bus interfacing. The device operates within a voltage range of 2V to 6V and supports an extended military temperature range from -55°C to +125°C. It is housed in a hermetic ceramic flatpack package designed for radiation hardness, making it suitable for aerospace applications requiring immunity to single event latch-up and upset.

Feature Summary

• Radiation-hardened design qualified for aerospace environments
• Hermetic ceramic packaging for extreme durability
• Dual output enable control for bus management

Applications

• Aerospace bus interface systems
• Military-grade data acquisition circuits
• Spacecraft communication modules

Procurement Notes

Verify the specific suffix 'S2A' against official datasheets to confirm pinout and package dimensions. Ensure the manufacturer source is identified correctly as National Semiconductor or its successor Texas Instruments. Confirm radiation qualification status if required for mission-critical deployment. Check for RoHS compliance exemptions typical for military-grade hermetic components.

Selection Notes

Select this component when radiation tolerance and hermetic sealing are mandatory. Compare performance metrics such as propagation delay and power consumption against standard commercial variants. Ensure the operating voltage aligns with the 2V to 6V specification. Verify that the dual enable feature meets system control requirements.

Part Context

This part belongs to the 54AC series of high-speed CMOS logic functions. The 54 prefix indicates military-grade qualification. The AC series offers higher speed than standard HC/HCT counterparts while maintaining CMOS power efficiency. Hermetic packages distinguish these parts from plastic commercial equivalents.

Replacement Considerations

Direct substitutes include other radiation-hardened octal buffers from manufacturers like Microchip or ADI. Verify package compatibility for hermetic flatpack configurations. Ensure equivalent radiation hardness levels are maintained for space applications.
