HCF4027BEY

Overview

The HCF4027BEY is a dual JK flip-flop integrated circuit manufactured by STMicroelectronics, belonging to the HCF logic series. It features two independent JK flip-flops with set and reset inputs within a single package. The device operates on a supply voltage range of 3V to 20V and supports input levels compatible with CMOS standards. It is housed in a 14-pin DIP package suitable for through-hole mounting. The component is designed for high noise immunity and low power consumption typical of HCMOS technology.

Feature Summary

• Dual configuration containing two independent JK flip-flops with set and reset capabilities
• High noise immunity and low power dissipation characteristics inherent to HCMOS technology
• Input levels compatible with standard CMOS outputs for versatile interfacing

Applications

• Digital data storage and latching circuits
• Frequency division and counting applications
• Shift register construction

Procurement Notes

Verify the specific suffix BEY corresponds to the 14-pin DIP package and commercial temperature grade when sourcing. Confirm RoHS compliance status as per current manufacturer declarations. Ensure the supplier provides valid traceability documentation for automotive or industrial qualification if required by the application design specifications.

Selection Notes

Select this component when a dual JK flip-flop topology is required with through-hole packaging constraints. Consider the HCF series for applications demanding robust noise immunity over wide voltage ranges. Evaluate pin compatibility against existing PCB footprints before finalizing the part number for production integration.
