CD54HCT4020F3A

Counter Dividers Overview

The CD54HCT4020F3A 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 ambient temperature range from -55°C to 125°C. The component utilizes negative edge clocking 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

Military-grade construction with hermetic ceramic packaging
Direct compatibility with LSTTL input logic levels
Fully static operation with balanced propagation delays

Counter Dividers Applications

Military aerospace digital systems
Defense communication equipment
Harsh environment industrial counters

Counter Dividers Procurement Notes

Verify the specific ordering suffix F3A against the manufacturer's current package option addendum to confirm the exact physical dimensions and material specifications. Ensure the procurement channel provides traceability documentation required for military-grade components. Confirm RoHS exemption status if applicable to your assembly process requirements.

Counter Dividers Selection Notes

Select this component when a 14-stage binary counting function is required in environments exceeding standard commercial temperature limits. The HCT series designation ensures direct interface compatibility with LSTTL logic families without requiring external level shifting. Verify that the application circuitry can accommodate the specific power dissipation characteristics associated with the ceramic package type.
