MC14028BDG

Overview

The MC14028BDG is a CMOS BCD-to-decimal decoder manufactured by onsemi in a 16-pin SOIC package. It converts an 8421 BCD code into one-of-ten decoded outputs. Key electrical parameters include a supply voltage range of 3 V to 18 V, low-level output current of 8.8 mA, and high-level output current of -8.8 mA. The device operates within a temperature range of -55 °C to +125 °C with a propagation delay of 200 ns.

Feature Summary

• Constructs decimal (one-of-ten) decoded outputs from four 8421 BCD input lines
• Features diode protection on all inputs for enhanced reliability
• Ensures low outputs on all illegal input combinations

Applications

• BCD to decimal decoding circuits
• Digital display drivers requiring one-of-ten selection
• Industrial control systems operating at elevated temperatures

Procurement Notes

Verify the component marking against the official onsemi datasheet to confirm authenticity. Ensure the SOIC-16 package matches the specified footprint. Check for RoHS compliance documentation if required for your assembly process. Confirm that the supply voltage and temperature ratings align with your system design constraints before finalizing procurement.

Selection Notes

Select this component when a single BCD-to-decimal decoder is required with wide supply voltage flexibility. It is suitable for applications needing positive logic design and input protection. Consider the 16-pin SOIC package for surface-mount assembly. Verify that the 8.8 mA output current capability meets the load requirements of the connected circuitry.

Part Context

This part belongs to the MC14000 series of CMOS logic devices. It serves as a direct functional equivalent to the CD4028B. The device is designed for general-purpose digital logic applications where reliable BCD conversion is necessary. It offers robust performance across industrial temperature ranges.

Replacement Considerations

The CD4028B is a confirmed public substitute with identical logical function and pinout. Verify package compatibility and ensure the replacement meets the same voltage and temperature specifications.
