Overview
The CD4046BF3A is a Phase Locked Loop (PLL) integrated circuit manufactured by Texas Instruments. It is supplied in a 16-lead hermetic dual-in-line ceramic package with the F3A suffix. The device operates within a temperature range of -55°C to +125°C and is designated as Active Production status. It is QML certified for Military and Defense Applications, providing a robust solution for frequency synthesis and clock recovery tasks requiring high reliability.
Feature Summary
- Hermetically sealed 16-lead ceramic construction
- QML certification for military and defense applications
- Integrated phase locked loop functionality
Applications
- Military communication systems
- Defense electronics
- High-reliability frequency synthesis
Procurement Notes
Verify that the specific order explicitly requires the CD4046BF3A variant due to its specialized hermetic packaging and military qualification. Confirm that the application environment necessitates the -55°C to +125°C operating range and that standard plastic packages are insufficient for the required environmental protection and reliability standards.
Selection Notes
Select this component when a hermetically sealed ceramic package is mandatory for radiation or harsh environment resistance. Ensure the design supports the 16-pin DIP form factor. Consider alternative plastic versions like the CD4046BE only if military certification and hermetic sealing are not required by the system specifications.
Part Context
This part belongs to the CD4046B family of PLLs. While other variants use plastic packages such as SOIC or TSSOP, the BF3A specifically utilizes a hermetic ceramic structure. This distinction makes it suitable for aerospace and defense sectors where standard commercial-grade packaging does not meet strict environmental durability requirements.
Replacement Considerations
Direct replacements include the CD4046BF and CD4046BF.A, which share the same hermetic ceramic package and military qualification status. Verify pinout compatibility before substituting.
