HEF4027BT,652

Overview

The HEF4027BT,652 is a dual positive-edge triggered JK flip-flop from the Nexperia HE4000B logic series. It features independent asynchronous set (nSD) and clear (nCD) inputs that override clock and data signals. The device operates within a supply voltage range of 3 V to 15 V and includes Schmitt-trigger action on the clock input for noise immunity. Packaged in a SOIC-16 surface-mount format, it supports differential outputs and single-ended inputs.

Feature Summary

• Dual JK flip-flop configuration with complementary outputs
• Asynchronous set and clear inputs for direct state control
• Schmitt-trigger clock input for slow signal tolerance

Applications

• Registers
• Counters
• Control circuits

Procurement Notes

Verify current availability status as the product may be subject to obsolescence or limited distribution channels. Confirm package suffix compatibility and check for alternative sourcing options through authorized distributors if immediate procurement is required for production planning.

Selection Notes

Select this component for designs requiring dual edge-triggered storage elements with independent reset and set capabilities. Ensure the application utilizes a supply voltage between 3 V and 15 V and benefits from the noise immunity provided by the Schmitt-trigger clock input interface.

Part Context

This part belongs to the HE4000B CMOS logic family, known for low power dissipation and high noise immunity. It complements other standard logic functions within the same series, offering standardized symmetrical output characteristics and compliance with JEDEC standards for robust digital circuit integration.

Replacement Considerations

Check for pin-compatible alternatives within the HE4000B series or equivalent dual JK flip-flops from other manufacturers. Verify that substitute components maintain the same voltage range, package type, and electrical performance specifications.
