CD54HCT4040F3A

Counter Dividers Overview

The CD54HCT4040F3A is a military-grade, high-speed CMOS logic device functioning as a 14-stage ripple-carry binary counter. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended temperature range from -55°C to +125°C. The component utilizes a 16-pin ceramic dual in-line package (CDIP) designed for through-hole mounting. It features buffered inputs and outputs with a common reset line that forces all counters to the zero state upon receiving a high voltage level.

Counter Dividers Feature Summary

• Fully static operation with buffered inputs and outputs
• Direct compatibility with LSTTL input logic levels
• Negative edge clock pulsing for state advancement
• Common master reset functionality

Counter Dividers Applications

• Military and defense electronic systems
• High-speed digital counting applications
• Industrial control circuitry
• Data communications equipment

Counter Dividers Procurement Notes

Verify the specific ordering suffix F3A against the latest Texas Instruments Package Option Addendum to confirm current production status and material specifications. Ensure procurement channels are authorized to handle QML certified components intended for military and defense applications. Confirm compliance with RoHS exemptions if applicable to the specific manufacturing lot.

Counter Dividers Selection Notes

Select this component when a 14-stage binary counter is required for environments demanding wide temperature stability and radiation-hardened reliability standards. The HCT series ensures direct interface compatibility with LSTTL logic families without requiring additional level shifting circuits. Verify that the system power supply remains strictly within the 4.5 V to 5.5 V operational limits to maintain signal integrity.

Counter Dividers Part Context

This part belongs to the CD54HCT4040 family, which represents the military-qualified version of the standard 74HCT4040 binary counter. Unlike commercial variants, the CD54 series undergoes rigorous testing and qualification processes to meet stringent military specifications. It shares functional similarities with other members of the HC/HCT logic families but offers enhanced durability for harsh operating conditions.

Counter Dividers Replacement Considerations

The catalog equivalent CD74HCT4040 serves as a commercial alternative but lacks military certification. For direct replacements within the military grade segment, verify availability of other CD54-series counters or consult the manufacturer's cross-reference documentation for updated qualified substitutes.
