CD4022BE

Counter Dividers Overview

The CD4022BE is an 8-bit synchronous ring counter from the 4000/14000/40000 series, manufactured by Harris Corporation. It features positive edge triggering and up-counting direction using CMOS technology. The device provides eight decoded outputs and includes load/preset input capabilities. It operates within a temperature range of -55 °C to 125 °C and supports a maximum load capacitance of 50 pF. The component is housed in a 16-pin PDIP package.

Counter Dividers Feature Summary

• Synchronous operation with positive edge triggering for reliable state transitions
• Eight decoded outputs providing specific stage indication in the counting sequence
• CMOS construction ensuring low power consumption and wide voltage tolerance

Counter Dividers Applications

• Digital sequencing circuits requiring precise step control
• Decoded output generation for display or indicator systems
• Control logic in industrial automation environments

Counter Dividers Procurement Notes

Verify manufacturer origin as Harris Corporation, noting that Texas Instruments also produces this part number under different suffixes. Confirm package type matches requirements, as ceramic DIP variants exist. Check RoHS compliance status separately, as older Harris batches may not meet current environmental standards. Ensure supply chain documentation aligns with specific project qualification needs.

Counter Dividers Selection Notes

Select this component when an 8-stage decoded ring counter is required rather than a binary counter. Verify that the synchronous positive edge trigger aligns with system clock timing. Consider the 50 pF load capacitance limit for output driving capability. Compare against other 4000-series logic families if pin compatibility or alternative decoding schemes are needed.

Counter Dividers Part Context

This component belongs to the standard 4000-series CMOS logic family, widely used in general-purpose digital electronics. It serves as a specialized variant within the broader counter category, offering direct decoded outputs instead of raw binary bits. Its inclusion in the 14000/400000 series indicates industrial-grade temperature rating suitability.

Counter Dividers Replacement Considerations

CD4022BD3 (Ceramic DIP16 variant with gated clock and TCO output). CD4022BFMS (Plastic DIP16 variant). Note that Texas Instruments CD4022BE datasheets may describe a 4-bit binary counter, indicating potential nomenclature confusion; verify functional description against schematic requirements.
