HEC4021BTT,118

Shift Registers Overview

The HEC4021BTT,118 is an 8-bit static shift register belonging to the HE4000B logic family. It operates in serial/parallel-to-parallel mode with a unidirectional data flow triggered by rising edges. The device supports a supply voltage range of 3 V to 15 V and functions within an extended industrial temperature range from -40 °C to +125 °C. Packaged in a 16-pin PDIP for through-hole mounting, it measures 19.5 mm in length, 6.48 mm in width, and 3.2 mm in height.

Shift Registers Feature Summary

• Provides 8-bit static shift register functionality within the HE4000B logic family.
• Supports serial or parallel input conversion to parallel output via unidirectional shifting.
• Operates reliably across an extended industrial temperature range up to +125 °C.

Shift Registers Applications

• Industrial control systems requiring robust logic components
• Data acquisition interfaces utilizing serial-to-parallel conversion
• General-purpose digital logic circuits in harsh environments

Shift Registers Procurement Notes

Verify the exact part number against official NXP documentation to ensure compatibility with the HE4000B specifications. Confirm that the through-hole PDIP package meets your board layout requirements. Check for any specific ordering suffixes that may indicate variations in packaging or compliance status. Ensure the supplier provides valid traceability documents for industrial-grade components.

Shift Registers Selection Notes

Select this component when an 8-bit shift register is required for serial-to-parallel data conversion in industrial applications. The HE4000B series offers high noise immunity suitable for electrically noisy environments. Consider the through-hole mounting option if mechanical stability is prioritized over surface area constraints. Verify that the operating voltage and temperature ranges align with your system's environmental conditions.

Shift Registers Part Context

This component is part of the HE4000B logic family, which utilizes LOCMOS technology. The family is designed for general-purpose digital applications requiring reliable performance across wide voltage and temperature ranges. The HE4000B series complements other logic devices by providing essential data manipulation functions like shifting and storage for complex digital systems.

Shift Registers Replacement Considerations

Compatible substitutes include the HEF4021BP and HEF4021BF, which share identical logical functions and pinouts within the HE4000B family. Verify that alternative packages maintain the required through-hole mounting characteristics and industrial temperature ratings.
