SN54197J

Counter Dividers Overview

The SN54197J is a high-reliability, hermetically sealed 4-bit serial-in/serial-out or parallel-in/parallel-out shift register manufactured by Texas Instruments. It operates within an extended military temperature range of -55°C to 125°C and utilizes a 14-pin Ceramic Dual In-line Package (CDIP). The device features a J0014A package outline with a maximum height of 5.08 mm and falls within MIL-STD-1835 standards. It is currently in active production status.

Counter Dividers Feature Summary

• Hermetically sealed ceramic dual in-line construction for enhanced environmental protection
• Extended operating temperature range suitable for harsh military environments
• Compliance with MIL-STD-1835 qualification standards

Counter Dividers Applications

• Military aerospace systems requiring high reliability
• Harsh environment data processing applications
• Industrial control systems with extreme temperature exposure

Counter Dividers Procurement Notes

Verify the specific ordering suffix and material type against current TI documentation before procurement. Confirm that the CDIP package aligns with your board layout requirements. Ensure compatibility with your assembly processes regarding the hermetic seal and terminal identification. Cross-reference the part marking and lot trace code information for quality assurance purposes. Validate that the active production status meets your long-term supply needs.

Counter Dividers Selection Notes

Select this component when military-grade reliability and hermetic sealing are mandatory. The SN54197J is appropriate for designs requiring operation across the full -55°C to 125°C temperature spectrum. Consider the 14-pin CDIP form factor for its mechanical robustness and radiation hardness characteristics inherent to ceramic packages. Ensure the application benefits from the specific shift register functionality provided by this device.

Counter Dividers Part Context

The SN54197J belongs to the SN5419x family of shift registers designed for high-reliability applications. It shares functional similarities with other members of the series but is distinguished by its ceramic packaging and extended temperature rating. This variant is specifically engineered for environments where standard plastic packages would fail due to thermal or environmental stress.

Counter Dividers Replacement Considerations

SN54196J and SNJ54197J are listed as active production parts with identical packaging and temperature ratings. Verify functional equivalence and pinout compatibility before substitution. The 'J' suffix denotes the ceramic dual in-line package option.
