MC14028BFL2

Overview

The MC14028BFL2 is a CMOS decimal decoder/driver manufactured by onsemi. It belongs to the MC140 series and features four binary inputs that drive ten active-high decoded outputs. The device operates within a supply voltage range of 3 V to 18 V and supports surface mount installation in an SOIC package. It functions as a single unit with 16 pins, designed for unidirectional logic applications across industrial temperature ranges.

Feature Summary

• Provides direct decoding of four binary input bits into ten distinct active-high output lines
• Utilizes CMOS technology to ensure compatibility with standard logic families
• Supports wide operating supply voltages from 3 V to 18 V for flexible system integration

Applications

• Decimal counting systems requiring direct BCD-to-decimal translation
• Multiplexed display drivers for numeric readouts
• Control logic circuits for activating specific peripheral channels

Procurement Notes

Verify the exact suffix designation against official onsemi documentation to confirm pinout and electrical specifications. Ensure the procurement channel provides genuine components with traceable manufacturing dates. Cross-reference the package outline dimensions with the datasheet to validate physical compatibility with existing PCB footprints before finalizing orders.

Selection Notes

Select this component when a dedicated decimal decoding function is required without external logic gates. Consider the MC140 series compatibility if upgrading legacy designs. Evaluate the 16-pin SOIC footprint constraints and verify that the 3 V to 18 V supply range aligns with the target system power architecture.

Part Context

This part is part of the broader MC140xx family of CMOS logic devices produced by onsemi. These components are widely used in general-purpose digital electronics. The MC14028 specifically addresses the need for decimal decoding, distinguishing it from binary or hexadecimal decoders within the same logical family.

Replacement Considerations

Check for compatible equivalents within the MC140 series from other manufacturers. Verify pin-for-pin compatibility and identical logic truth tables. Confirm that alternative sources meet the same voltage and temperature specifications.
