CD54HCT4059F

Counter Dividers Overview

The CD54HCT4059F is a divide-by-N counter integrated circuit manufactured by Harris Corporation. It features a single element with 16-bit capability and utilizes positive edge triggering for clock input synchronization. The device operates within a supply voltage range of 4.5V to 5.5V, ensuring compatibility with standard HCT logic levels. It is housed in a 24-lead Ceramic Dual In-Line Package (CDIP) designed for high-reliability applications. The component supports military-grade temperature specifications, functioning reliably across an ambient temperature range of -55°C to 125°C.

Counter Dividers Feature Summary

• Implements divide-by-N counting functionality using a single internal element structure.
• Utilizes positive edge-triggered clocking mechanism for precise timing control.
• Constructed with ceramic packaging to ensure durability in harsh environments.
• Designed for operation within standard HCT logic voltage parameters.

Counter Dividers Applications

• Frequency division circuits requiring stable N-ratio outputs
• Digital timing systems utilizing positive edge synchronization
• Military-grade electronic assemblies demanding wide temperature tolerance

Counter Dividers Procurement Notes

Verify the manufacturer designation as Harris Corporation on the component marking. Confirm the package type is 24-CDIP and the series is 54HCT. Ensure the part meets the specified voltage and temperature requirements for your specific application environment before integration.

Counter Dividers Selection Notes

Select this component when a divide-by-N function is required with high noise immunity provided by HCT logic levels. The ceramic package makes it suitable for environments where plastic packages may fail due to thermal stress or moisture. Ensure the design accommodates the 24-pin footprint and positive edge trigger requirement.

Counter Dividers Part Context

This component belongs to the 54-series logic family, which typically denotes military-grade quality and extended temperature ranges compared to commercial 74-series equivalents. The HCT suffix indicates compatibility with TTL inputs while maintaining CMOS power consumption characteristics. Harris Corporation was a significant producer of such specialized logic devices before industry consolidations.

Counter Dividers Replacement Considerations

The CD74HC4059 is a pin-compatible alternative from Texas Instruments. Verify that the HC series voltage and speed characteristics align with the system requirements if substituting the HCT version. Check package availability as HC versions often use plastic rather than ceramic packages.
