HEF4555BT,652

Overview

The HEF4555BT,652 is a dual 1-of-4 decoder/demultiplexer from the Nexperia HE4000B logic series. It features two independent circuits in an SOIC-16 surface-mount package. The device operates within a supply voltage range of 3 V to 15 V and supports a propagation delay of 90 ns. It functions over an extended temperature range from -40 °C to +85 °C with a power dissipation rating of 500 mW.

Feature Summary

• Contains two independent 1-of-4 decoders or demultiplexers with active LOW enable inputs and mutually exclusive active HIGH outputs.
• Provides high noise immunity and fully static operation characteristics typical of CMOS technology.
• Includes electrostatic discharge protection exceeding 2000 V (HBM) and 1000 V (CDM) per JEDEC standards.

Applications

• Address decoding in digital systems
• Demultiplexing data streams using the enable input as a data signal
• Code conversion tasks

Procurement Notes

Verify current availability status directly with the manufacturer or authorized distributors, as this component may be subject to production end-of-life notices. Confirm that the SOIC-16 package and HE4000B logic family specifications align with your design requirements before finalizing procurement plans.

Selection Notes

Select this component for designs requiring dual 1-of-4 decoding or demultiplexing capabilities within the HE4000B family. Ensure the operating environment stays within the specified -40 °C to +85 °C temperature range and that the supply voltage remains between 3 V and 15 V. Verify that the 90 ns propagation delay meets system timing constraints.

Part Context

This part belongs to the Nexperia HE4000B series, which offers standardized symmetrical output characteristics and complies with JEDEC standard JESD 13-B. The series is designed for general-purpose digital logic applications requiring low power dissipation and wide supply voltage flexibility.

Replacement Considerations

Check for direct pin-compatible substitutes within the HE4000B family. Verify that any alternative decoder/demultiplexer maintains the same SOIC-16 footprint and electrical parameters, specifically the 3 V to 15 V operating range and 90 ns delay specification.
