Display Drivers Procurement Notes

Verify the specific suffix 'BEY' against official STMicroelectronics documentation to confirm pinout and electrical characteristics match project requirements. Ensure compliance with RoHS directives if applicable, as indicated in component metadata. Confirm the ceramic DIP-16 package availability for assembly processes. Cross-reference the ECCN code EAR99 for export control classification before procurement.

Display Drivers Selection Notes

Select this component when a robust, high-voltage CMOS decoder is required for harsh environments. The ceramic hermetic package provides superior protection compared to plastic alternatives. Consider the wide operating temperature range for applications exposed to extreme thermal conditions. Verify that the parallel input interface aligns with the system's control logic architecture.

Display Drivers Part Context

This part belongs to the legacy CMOS4000B series of high-voltage logic functions. These components are designed for reliability in demanding applications. The HCF4056BEY specifically addresses decoding needs for numeric displays. It represents a standard solution for converting digital codes into visual output formats in industrial and commercial equipment.

Display Drivers Replacement Considerations

Consult official cross-reference lists for compatible equivalents. Verify pin compatibility and electrical specifications before substituting. Generic CMOS decoders may not offer the same radiation hardness or hermetic sealing.
