JM54ACT138SFA-R

Overview

The JM54ACT138SFA-R is a high-speed CMOS 3-to-8 line decoder/driver manufactured by National Semiconductor. It features inverted outputs and operates within a military temperature range of -55°C to 125°C. The device utilizes a standard 5V supply voltage and is housed in a ceramic flatpack package with 16 terminals. Designed for robust performance in demanding environments, it adheres to MIL-STD-883 Class C screening standards, ensuring reliability for aerospace and defense applications requiring strict environmental tolerance.

Feature Summary

• High-speed CMOS technology providing fast switching capabilities
• Military-grade qualification for extreme temperature operation
• Inverted output configuration for specific logic interfacing

Applications

• Aerospace and defense electronic systems
• Data acquisition and storage addressing
• Industrial control system decoding

Procurement Notes

Verify the authenticity of the National Semiconductor manufacturer marking on the component body. Confirm that the part meets MIL-STD-883 Class C screening requirements as specified for this military grade designation. Ensure the ceramic flatpack package integrity is intact prior to installation. Cross-reference the date code and lot number against current manufacturing records to validate provenance.

Selection Notes

Select this component when military-grade environmental resilience is required alongside high-speed CMOS logic performance. It is suitable for designs necessitating a 3-to-8 line decoding function with inverted outputs in harsh thermal conditions. Consider the ceramic flatpack form factor for applications requiring hermetic sealing or superior thermal dissipation compared to plastic packages.

Part Context

This part belongs to the 54ACT family of logic devices, which are designed to be pin-compatible with earlier 54LS series components while offering significantly faster speeds and lower power consumption typical of Advanced CMOS technology. The 'JM' prefix typically denotes military grade specifications from National Semiconductor.

Replacement Considerations

Compatible substitutes include other 54ACT138 variants from manufacturers such as Texas Instruments, ON Semiconductor, or Microchip, provided they meet the same military temperature range and MIL-STD-883 screening requirements.
