SN5497J

Counter Dividers Overview

The SN5497J is a synchronous four-bit universal shift register manufactured by Texas Instruments. It operates within a military-grade temperature range of -55°C to 125°C and utilizes a 16-pin Ceramic Dual In-line Package (CDIP). The device supports serial-in/serial-out, serial-in/parallel-out, parallel-in/serial-out, and parallel-in/parallel-out data transfer modes. It features independent clock inputs for the shift register and the J-K flip-flops, allowing for flexible timing control in high-reliability digital systems.

Counter Dividers Feature Summary

• Supports multiple data transfer configurations including serial and parallel input/output operations
• Features independent clocking mechanisms for shift register stages and J-K flip-flops
• Designed for operation in extreme environmental conditions with extended temperature stability

Counter Dividers Applications

• Military and defense electronic systems requiring high reliability
• Aerospace data processing and storage circuits
• Industrial control systems operating in harsh environments

Counter Dividers Procurement Notes

Verify that the specific orderable part number matches the required package type and material specifications. Confirm the RoHS status and lead finish details against current project requirements. Ensure the component meets the necessary military or industrial qualification standards before integration into final assemblies.

Counter Dividers Selection Notes

Select this component when military-grade temperature tolerance and radiation hardness are critical. Compare pin compatibility and electrical characteristics with existing designs. Consider the ceramic package durability for applications involving mechanical stress or thermal cycling beyond standard commercial limits.

Counter Dividers Part Context

This device belongs to the SN54xx series, which denotes military-grade performance levels. It is functionally similar to the SN7497 but differs in operational temperature range and packaging construction. The SN5497J provides enhanced reliability for specialized applications where standard commercial components are insufficient.

Counter Dividers Replacement Considerations

SN5497J.A serves as an alternative ordering suffix for the same functional device. Verify package marking and material consistency when substituting between these variants.
