MC14555BDG

Overview

The MC14555BDG is a dual binary-to-1-4 decoder or demultiplexer manufactured by onsemi. It operates within a supply voltage range of 3 V to 18 V and supports surface-mount installation in an SOIC-16 package. The device contains two independent circuits, each featuring one input line and four output lines. It functions reliably across an extended temperature range from -55 °C to +125 °C.

Feature Summary

• Integrates two independent decoding or demultiplexing circuits within a single package
• Supports wide operating voltage range for flexible power supply integration
• Designed for reliable performance across extreme industrial temperature conditions

Applications

• Data routing and signal distribution systems
• Address decoding in memory architectures
• Control logic for peripheral selection

Procurement Notes

Verify the specific suffix 'BDG' confirms the SOIC-16 surface mount package and lead-free compliance status required for your assembly process. Confirm that the active status aligns with long-term production availability needs. Ensure the 3V to 18V operational range matches your system's power supply specifications before finalizing procurement orders.

Selection Notes

Select this component when dual independent decoding channels are required in a compact surface-mount footprint. The wide voltage tolerance allows compatibility with various logic families. Consider the SOIC-16 thermal characteristics and the -55°C to +125°C rating for harsh environment deployments where standard commercial grade parts may fail.

Part Context

This part belongs to the MC14555B series of CMOS logic devices. It serves as a functional alternative to through-hole DIP variants like the MC14555BP, offering equivalent logical operations but optimized for automated surface-mount assembly. The device is part of the broader MC145xx family designed for general-purpose digital switching applications.

Replacement Considerations

Direct pin-compatible alternatives include other manufacturers' dual 1-of-4 decoders in SOIC-16 packages. Verify electrical parameters such as propagation delay and output drive current against original datasheet specifications to ensure circuit compatibility during substitution.
