MC14028BFL1

Overview

The MC14028BFL1 is a high-speed CMOS decimal decoder/driver manufactured by Motorola Semiconductor Products. It features a single 1x4-to-10 decoding configuration, converting four binary inputs into ten mutually exclusive active-high outputs. The device is housed in a 16-SOEIAJ surface-mount package. As part of the MC140xx series, it utilizes standard CMOS technology to provide reliable logic decoding functions with low power consumption characteristics typical of this family.

Feature Summary

• Implements one-to-four input to ten-output decimal decoding logic
• Generates mutually exclusive active-high output signals for each decoded state
• Utilizes high-speed CMOS process technology for efficient operation
• Designed for surface-mount assembly via SOEIAJ packaging

Applications

• Digital display driver circuits requiring decimal digit selection
• Control logic systems needing binary-to-decimal translation
• Memory address decoding applications
• Sequential control circuitry in embedded systems

Procurement Notes

Verify the manufacturer marking matches Motorola or authorized successors such as NXP or ON Semiconductor, as ownership transfers occur. Confirm the package type is strictly 16-SOEIAJ and check for any suffix variations that may indicate temperature range or tape-and-reel specifications. Request original datasheets to validate pinout compatibility before integration into designs.

Selection Notes

Select this component when a dedicated 4-bit to 10-line decoder is required within a space-constrained design utilizing surface-mount technology. Ensure the system voltage aligns with standard CMOS operating ranges. Consider alternative packages if leaded options are preferred, though this specific model denotes a surface-mount variant suitable for automated placement processes.

Part Context

This device belongs to the MC140xx series of CMOS logic integrated circuits, widely used in digital electronics for basic logic operations. The MC14028 specifically addresses the need for decimal decoding, a function less common than binary-coded decimal converters but essential for direct drive applications. Its inclusion in the high-speed sub-series indicates optimized switching performance relative to earlier iterations.

Replacement Considerations

Direct substitutes include other MC14028 variants from different manufacturers adhering to the same pinout and logical function. Verify electrical parameters against the original specification sheet to ensure compatibility with existing supply voltages and load requirements without redesigning the surrounding circuitry.
