4022A/BEA

Overview

The 4022A/BEA is a divide-by-8 binary counter manufactured by Rochester Electronics, LLC. It is dual-marked as M38510/05604BEA and belongs to the CD4000 series of CMOS logic devices. The component operates within a supply voltage range of 3 V to 18 V, with a nominal rating of 5 V. It features eight asynchronous outputs corresponding to the binary count states. The device is designed for robust performance across an extended temperature range, supporting industrial and military applications through its specific marking and qualification.

Feature Summary

• Implements divide-by-8 binary counting functionality using CMOS technology
• Provides eight distinct asynchronous output terminals for state indication
• Supports wide supply voltage operation from 3 V to 18 V
• Dual-marked designation indicating compliance with MIL-PRF-38510 specifications

Applications

• Binary frequency division circuits
• Digital timing sequence generation
• Military-grade digital logic systems requiring extended temperature tolerance
• Industrial control counters requiring high noise immunity

Procurement Notes

Verify the dual marking M38510/05604BEA on the component body to confirm authenticity and traceability. Ensure the supplier provides documentation linking the part to the original manufacturer's specifications. Confirm that the package type matches the required form factor for your PCB layout. Check for any specific handling instructions related to CMOS sensitivity during assembly processes.

Selection Notes

Select this component when a reliable divide-by-8 counter is needed for harsh environments. The wide voltage range allows flexibility in power supply design. Consider the package constraints and pinout compatibility with existing designs. Verify that the asynchronous nature of the outputs aligns with the system's timing requirements compared to synchronous alternatives.

Part Context

Rochester Electronics specializes in continuing source solutions for obsolete and end-of-life semiconductors. The 4022A/BEA represents a legacy CMOS logic part maintained for long-term production needs. As a member of the 4000 series, it shares architectural similarities with other standard logic families but offers specific radiation hardness and temperature stability attributes defined by its military marking.

Replacement Considerations

Direct equivalents include the CD4022B or CD4022BE from original manufacturers. Verify pin compatibility and electrical parameters before substitution. Ensure the replacement meets the same MIL-PRF-38510 standards if military qualification is required.
