CD4022BF3A

Counter Dividers Overview

The CD4022BF3A is a military-grade CMOS 4-bit Johnson counter and frequency divider housed in a 16-lead hermetic dual-in-line ceramic package (CDIP). It operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55 °C to +125 °C. The device features asynchronous reset, positive-edge triggering, and ripple-clock outputs for cascading multiple devices in multi-stage counting chains.

Counter Dividers Feature Summary

• Military-grade hermetic ceramic packaging
• Asynchronous reset functionality
• Positive-edge triggered operation
• Ripple-clock output capability

Counter Dividers Applications

• Military and defense applications
• High-reliability digital counting systems
• Frequency division circuits
• Multi-device cascaded counting chains

Counter Dividers Procurement Notes

Verify the specific ordering suffix BF3A to confirm the 16-lead hermetic ceramic package and military qualification status. Ensure procurement channels are authorized for QML certified components. Confirm RoHS exemption details as military parts may not adhere to standard commercial environmental directives.

Counter Dividers Selection Notes

Select this component when hermetic sealing and extended temperature stability are required. It serves as a direct functional equivalent to the standard plastic CD4022BE but provides enhanced environmental protection. Consider the higher cost associated with ceramic packaging and military certification levels.

Counter Dividers Part Context

This part belongs to the CD4022B family of 4-bit Johnson counters. It shares logical functionality with catalog versions but utilizes a specialized military package. The F3A suffix specifically denotes the hermetic ceramic construction intended for harsh environments where standard plastic packages are unsuitable.

Counter Dividers Replacement Considerations

Direct replacements include CD4022BF.A or other CD4022B variants with the same logic function. Verify that substitute parts meet the required hermeticity and temperature specifications if replacing in existing military designs.
