MC14555BDR2G

Overview

The MC14555BDR2G is a dual binary-to-decoder/demultiplexer integrated circuit manufactured by onsemi. It operates within a supply voltage range of 3 V to 18 V and supports an extended industrial temperature range from -55 °C to +125 °C. The device features two independent circuits, each configured as a 1-input to 4-output decoder or demultiplexer. It is housed in a surface-mount SOIC-16 package.

Feature Summary

• Dual independent decoder/demultiplexer architecture
• Wide operating voltage capability
• Extended industrial temperature rating

Applications

• Data routing systems
• Address decoding logic
• Signal distribution networks

Procurement Notes

Verify the specific suffix 'D' indicates the SOIC-16 surface mount package and 'R2G' denotes tape-and-reel packaging with lead-free compliance. Confirm RoHS status through official manufacturer documentation prior to integration. Ensure thermal management aligns with the specified -55 °C to +125 °C operational range for the target application environment.

Selection Notes

Select this component when a dual-channel decoding solution is required within a single package footprint. The wide voltage range accommodates various logic levels without external level shifting. Verify that the SOIC-16 form factor fits the PCB layout constraints and that the temperature rating meets the environmental requirements of the end-use system.

Part Context

This part belongs to the MC14555B series, which provides dual 1-line-to-4-line decoder functionality. It is part of the broader MC14500B CMOS logic family, known for high noise immunity and low power consumption. The device serves as a fundamental building block for digital control systems requiring signal selection or address decoding capabilities.

Replacement Considerations

Check for MC14555BDG (tube packaging) if reel quantity is not required. Verify functional compatibility with other MC14555 variants from different manufacturers, ensuring pinout and electrical characteristics match.
