HEF4014BT,652

Shift Registers Overview

The HEF4014BT,652 is an 8-bit static shift register from the Nexperia HEF4000 logic family. It operates within a supply voltage range of 3 V to 15 V and supports synchronous parallel loading via the PE input. The device features serial data input (DS) and clock input (CP), with outputs Q5 through Q7 providing buffered data. It includes clamp diodes on inputs for interfacing with voltages exceeding VDD. The component is specified for operation between -40 °C and +85 °C and complies with JEDEC standard JESD 13-B.

Shift Registers Feature Summary

• Supports both serial-to-parallel and parallel-to-serial data conversion modes
• Provides high noise immunity and tolerance for slow clock transitions
• Features fully static operation with standardized symmetrical output characteristics

Shift Registers Applications

• Parallel-to-serial converter
• Serial data queueing
• General purpose register

Shift Registers Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and temperature range. Confirm availability status as product lifecycles may change. Ensure design compliance with absolute maximum ratings before implementation.

Shift Registers Selection Notes

Select this component for designs requiring an 8-bit shift register with synchronous parallel enable capabilities. Verify that the operating voltage falls within the 3 V to 15 V range. Consider the SO16 package dimensions for PCB layout constraints.

Shift Registers Part Context

This part belongs to the HEF4000 series of CMOS logic devices manufactured by Nexperia. The series is characterized by wide supply voltage ranges and low power dissipation. The HEF4014B specifically provides 8-bit shifting functionality compared to other variants in the family.

Shift Registers Replacement Considerations

Check for direct pin-compatible alternatives within the HEF4000 series or equivalent 8-bit shift registers from other manufacturers. Verify functional compatibility regarding parallel enable signals and output buffering.
