DM5493AW/883C

Counter Dividers Overview

The DM5493AW/883C is a binary counter integrated circuit manufactured by National Semiconductor, now part of Texas Instruments. It belongs to the TTL/H/L series and features an asynchronous, negative edge-triggered design with a 4-bit up counting direction. The component is housed in a ceramic flatpack package (CDFP16) with 16 terminals, suitable for military temperature ranges from -55°C to 125°C. It complies with MIL-STD-883 Class C screening standards.

Counter Dividers Feature Summary

Negative edge-triggered operation
Military-grade reliability via MIL-STD-883 Class C screening
Ceramic flatpack construction for harsh environments

Counter Dividers Applications

Military aerospace digital systems
High-reliability industrial counters
Harsh environment data processing units

Counter Dividers Procurement Notes

Verify that the specific unit carries the correct manufacturer marking and lot traceability consistent with National Semiconductor or Texas Instruments production records. Confirm compliance with MIL-STD-883 Class C requirements through available test reports or certificates of conformance. Ensure the ceramic flatpack package integrity is intact upon receipt to maintain environmental sealing capabilities.

Counter Dividers Selection Notes

Select this component when a ruggedized, asynchronous 4-bit binary counter is required for military or high-reliability applications. It is appropriate for designs necessitating negative edge triggering and operation across extreme temperature variations. Consider the ceramic flatpack form factor if hermetic sealing and mechanical robustness are critical design constraints.

Counter Dividers Part Context

This device is part of the broader DM54xx series of logic integrated circuits produced by National Semiconductor. These components are designed for high-performance digital applications requiring strict adherence to military specifications. The DM5493 specifically addresses binary counting needs within this lineage, offering a standardized interface for complex digital system architectures.
