HEF4014BP,652

Shift Registers Overview

The HEF4014BP,652 is an 8-bit static shift register from the HEF4000B logic family. It features synchronous parallel enable and inputs with clamp diodes for voltage tolerance. The device operates on a supply voltage range of 3.0 V to 15.0 V. Propagation delays vary by voltage: at 5 V, tPHL/tPLH max is 260 ns/230 ns; at 10 V, max is 110 ns/100 ns; at 15 V, max is 80 ns/80 ns. Output currents reach ±3.6 mA at 15 V. It supports serial-to-parallel and parallel-to-serial data conversion.

Shift Registers Feature Summary

• Synchronous parallel enable input allows direct loading of data into all stages simultaneously.
• Inputs include internal clamp diodes, enabling interface to voltages exceeding the supply rail using current limiting resistors.
• Fully static operation ensures stable outputs without requiring continuous clocking.
• High noise immunity and tolerance for slow clock rise and fall times.

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package type. Confirm the manufacturer designation aligns with current Nexperia or NXP branding standards. Ensure the component meets the specified temperature range requirements for the intended environment. Cross-reference the datasheet revision date to confirm the latest electrical characteristics are applied.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with synchronous parallel load capability is required. The wide supply voltage range accommodates various logic levels. Verify that the propagation delay specifications meet the system timing constraints at the operating voltage. Consider the SO16 package dimensions for PCB layout compatibility.

Shift Registers Part Context

This part belongs to the HEF4000B CMOS logic family, known for low power dissipation and high noise immunity. The HEF4014B variant specifically provides 8-bit shifting functionality. The 'BP' suffix typically denotes the plastic small outline package (SO16) version, distinct from other package options like DIP if available in legacy lines.

Shift Registers Replacement Considerations

HEF4014BT,653 is a documented alternative in the same series, utilizing the SO16 package. Verify pinout compatibility and electrical parameters before substitution. Other 8-bit shift registers may require functional adaptation due to differing control logic or output configurations.
