CD54HC4040F

Counter Dividers Overview

The CD54HC4040F 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 2 V to 6 V and supports an extended temperature range from -55°C to +125°C. The component utilizes negative edge pulsing for state advancement and features a common reset line that forces all outputs to a low state upon receiving a high voltage level. All inputs and outputs are buffered to ensure signal integrity.

Counter Dividers Feature Summary

• Fully static operation with buffered inputs and outputs
• Military-grade reliability certified for extreme environmental conditions
• Direct compatibility with standard LSTTL loads

Counter Dividers Applications

• Military and defense electronic systems
• Aviation instrumentation counters
• Spacecraft telemetry data processing

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'F' against the manufacturer's current Package Option Addendum to confirm the exact physical package type and material specifications. Ensure the procurement channel provides valid traceability documentation required for military-grade components. Confirm RoHS compliance status and lead finish details directly from the official datasheet before finalizing orders.

Counter Dividers Selection Notes

Select this component when designing circuits requiring robust performance in harsh environments characterized by significant thermal fluctuations. The HC series offers wide operating voltage flexibility compared to HCT variants. Verify that the application does not require synchronous counting or preset capabilities, as this device functions strictly as an asynchronous ripple counter.

Counter Dividers Part Context

This part belongs to the Texas Instruments CD54xx family, which designates devices qualified for military and defense applications. It shares the core logical architecture with the commercial CD74HC4040 but adheres to stricter manufacturing controls and testing protocols mandated by QML standards. The device represents a specialized variant within the broader 74HC logic ecosystem.
