CD4022BFX

Counter Dividers Overview

The CD4022BFX is an 8-bit synchronous ring counter belonging to the 4000/14000/40000 series, manufactured by Harris Corporation. It operates as a Johnson counter with eight decoded outputs and features positive edge triggering. The device utilizes CMOS technology and is housed in a ceramic dual in-line package (CDIP16). It supports bidirectional load/preset inputs and includes a terminal count output alongside a gated clock input. The component functions within a supply voltage range of 3 V to 18 V, with a nominal rating of 5 V, and maintains an operating temperature range from -55 °C to 125 °C.

Counter Dividers Feature Summary

• Synchronous 8-bit Johnson ring counter architecture providing eight decoded outputs
• Positive edge triggered operation with dedicated gated clock input
• Bidirectional load and preset capabilities for flexible data initialization
• Ceramic metal-sealed cofired packaging suitable for high-reliability environments

Counter Dividers Applications

• High-reliability digital counting sequences requiring decoded stage indication
• Military and aerospace timing control systems utilizing ruggedized ceramic packages
• Industrial automation logic circuits demanding wide temperature tolerance
• Complex state machine implementations using synchronous ring topologies

Counter Dividers Procurement Notes

Verify the specific suffix 'FX' against official Harris documentation to confirm exact pinout and electrical characteristics, as suffixes often denote specific package variants or testing levels. Ensure compatibility with existing ceramic DIP footprints and validate that the positive edge trigger aligns with system clocking requirements. Confirm RoHS status and material composition details directly with the manufacturer or authorized distributors prior to procurement.

Counter Dividers Selection Notes

Select this component when a synchronous 8-bit decoding solution is required within harsh environmental conditions. The ceramic construction offers superior durability compared to plastic equivalents. Consider the positive edge trigger requirement and the availability of decoded outputs for direct driving of indicator loads. Evaluate the need for separate load and preset controls versus simpler reset-only architectures found in other counter families.

Counter Dividers Part Context

This part belongs to the extensive Harris 4000 series CMOS logic family, known for broad supply voltage flexibility and low power consumption. The CD4022 variant specifically addresses applications needing sequential decoding without external gate logic. Its inclusion in the 14000/40000 lineage indicates compatibility with standard TTL-compatible interfaces where appropriate level shifting is applied.
