HEF4015BP,652

Shift Registers Overview

The HEF4015BP,652 is a dual edge-triggered 4-bit static shift register manufactured by Nexperia. It operates within a supply voltage range of 3 V to 15 V and features fully buffered parallel outputs (Q0 to Q3) for each register. The device includes an overriding asynchronous master reset input (nMR) that clears the register independent of the clock signal. Inputs are equipped with clamp diodes to allow interfacing with voltages exceeding VDD using current limiting resistors. The component complies with JEDEC standard JESD 13-B and provides ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Shift Registers Feature Summary

• Dual edge-triggered 4-bit static shift registers with serial-to-parallel conversion capability.
• Fully static operation tolerant of slow clock rise and fall times.
• Asynchronous master reset input overrides clock and data inputs to clear outputs.
• Input clamp diodes enable safe interfacing to voltages above the supply rail.

Shift Registers Applications

• Serial-to-parallel converter
• Buffer stores
• General purpose register

Shift Registers Procurement Notes

Verify the specific package variant against the datasheet revision history. The HEF4015BP designation was removed in version 9 of the product data sheet. Confirm current availability and exact package type directly with the manufacturer or authorized distributors, as ordering suffixes may indicate obsolete or superseded configurations not listed in the active documentation.

Shift Registers Selection Notes

Select this component for applications requiring dual independent 4-bit shift registers with static operation. Ensure the design accommodates the specified supply voltage range of 3 V to 15 V. Consider the propagation delay characteristics relative to the load capacitance when determining maximum operating frequency. Verify that the required ESD protection levels meet the system's environmental standards.

Shift Registers Part Context

The HEF4015B belongs to the HE4000B logic family, which utilizes CMOS technology for low power dissipation and high noise immunity. This family is standardized under JEDEC JESD 13-B. The device is designed for general-purpose digital logic applications where reliable serial-to-parallel data conversion is required without complex control circuitry.
