HEF4555BT-Q100J

Overview

The HEF4555BT-Q100J is an automotive-qualified 1-of-4 decoder/demultiplexer containing two independent units. Each unit features two active LOW address inputs (nA0, nA1), one active LOW enable input (nE), and four mutually exclusive active HIGH outputs (nY0 to nY3). It operates within a recommended supply voltage range of 3 V to 15 V referenced to ground. The device complies with AEC-Q100 Grade 3 standards and is specified for ambient temperatures from -40 °C to +85 °C.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 3 standard
• CMOS technology providing low power dissipation and high noise immunity
• Fully static operation with standardized symmetrical output characteristics
• ESD protection exceeding 2000 V per HBM and 1000 V per CDM

Applications

• Code conversion
• Address decoding
• Demultiplexing using the enable input as data input

Procurement Notes

Verify that the specific ordering suffix matches the required package variant and temperature grade. Confirm compliance with current RoHS directives and REACH regulations before finalizing procurement. Ensure design margins align with the absolute maximum ratings provided in the datasheet to prevent permanent damage during operation or storage.

Selection Notes

Select this component when dual 1-of-4 decoding or demultiplexing functions are required in space-constrained designs. The SO16 package offers a compact footprint suitable for surface-mount assembly. Verify that the logic levels and supply voltage requirements of the system interface match the CMOS input/output specifications defined in the static characteristics section.

Part Context

This part belongs to the Nexperia HEF4555B-Q100 family of 1-of-4 decoders and demultiplexers. It is designed for robust performance in automotive environments, adhering to strict reliability standards. The device integrates two identical decoder/multiplexer circuits within a single plastic small outline package, optimizing board space while maintaining signal integrity through high noise immunity.
