CD54HC4059F3A

Counter Dividers Overview

The CD54HC4059F3A is a prescaler integrated circuit manufactured by Harris Corporation. It is housed in a hermetically sealed ceramic DIP-24 package designed for military-grade reliability. The device operates on a nominal 5 V supply and supports frequencies up to 17 MHz. It functions within an extended temperature range of -55 °C to 125 °C, ensuring stable performance in harsh environments.

Counter Dividers Feature Summary

• Hermetically sealed ceramic construction for environmental protection
• Military-grade qualification for extreme temperature operation
• CMOS technology for low power consumption

Counter Dividers Applications

• Frequency synthesis systems
• Phase-locked loop (PLL) circuits
• High-frequency signal processing

Counter Dividers Procurement Notes

Verify the manufacturer date code and lot traceability to ensure compliance with military specifications. Confirm that the ceramic package integrity remains intact upon receipt. Check for any specific handling requirements related to electrostatic discharge during installation.

Counter Dividers Selection Notes

Select this component when high-reliability frequency division is required in aerospace or defense applications. Ensure the system design accommodates the 24-pin DIP footprint and the specified voltage levels. Consider the thermal management needs given the wide operating temperature range.

Counter Dividers Part Context

This part belongs to the HC/UH series of logic circuits produced by Harris Corporation, now part of Renesas Electronics. These components are known for their robustness and are often used in critical systems where standard commercial parts would fail due to environmental stressors.

Counter Dividers Replacement Considerations

Direct substitutes include other military-grade prescalers from Harris or Renesas with identical pinouts and specifications. Verify compatibility with existing PCB layouts and ensure equivalent frequency and voltage ratings before substitution.
