DM5497J/883

Counter Dividers Overview

The DM5497J/883 is a 6-bit binary counter integrated circuit manufactured by National Semiconductor. It operates within an extended temperature range of -55°C to 125°C (TA). The component is housed in a 16-CDIP package with a width of 0.300 inches (7.62mm) and utilizes through-hole mounting. This device functions as a TTL-compatible logic counter designed for high-reliability applications requiring robust performance under extreme thermal conditions.

Counter Dividers Feature Summary

• Six-bit binary counting capability
• Extended military-grade temperature operation
• TTL logic compatibility

Counter Dividers Applications

• Military aerospace systems
• High-temperature industrial control
• Ruggedized digital timing circuits

Counter Dividers Procurement Notes

Verify the manufacturer origin, as National Semiconductor assets are now held by Texas Instruments. Confirm the specific suffix /883 denotes MIL-STD-883 compliance and screening requirements. Ensure the package matches the 16-CDIP specification and validate the operating temperature range meets system constraints before procurement.

Counter Dividers Selection Notes

Select this component when a 6-bit binary counter is required for environments exceeding standard commercial temperature limits. The CDIP package is suitable for through-hole assembly processes. Verify that the TTL input levels align with the rest of the digital logic family in the design.

Counter Dividers Part Context

This part belongs to the DM54xx series, which represents military-grade versions of the SN54xx logic family. These components are characterized by wider temperature ranges and stricter manufacturing controls compared to their commercial counterparts. The DM5497 specifically provides six-bit counting functionality within this ruggedized logic portfolio.

Counter Dividers Replacement Considerations

Direct replacements include other DM5497 variants or SN5497 equivalents if temperature ratings allow. Verify pinout compatibility and electrical specifications against the original datasheet. Cross-reference with current Texas Instruments documentation for updated availability and equivalent part numbers.
