MC14028BDR2G

Overview

The MC14028BDR2G is a CMOS logic integrated circuit manufactured by onsemi, belonging to the 4000B series. It functions as a BCD-to-decimal decoder/driver with five independent outputs. The device accepts four binary-coded decimal (BCD) inputs and activates one of five active-high outputs corresponding to the decimal values zero through four. It operates within a supply voltage range of 3 V to 18 V and supports a wide operating temperature range from -55°C to +125°C. The component is housed in a 16-lead SOIC surface-mount package.

Feature Summary

• Performs conversion of four-bit binary-coded decimal input signals into five distinct active-high decimal output lines.
• Features high noise immunity and standard logic levels compatible with other devices in the 4000B CMOS family.
• Designed for robust operation across extended industrial temperature ranges and wide supply voltage variations.

Applications

• Decoding binary-coded data for direct control of decimal display indicators or seven-segment displays.
• Selecting specific channels or memory addresses in digital control systems using BCD addressing schemes.
• Implementing sequence generation circuits where specific decimal states trigger subsequent logic operations.

Procurement Notes

Verify the complete part number including the suffix to confirm the specific tape and reel packaging configuration intended for automated assembly processes. Ensure that the procurement source provides documentation confirming compliance with current environmental directives relevant to the manufacturing region. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency before finalizing integration plans.

Selection Notes

Select this component when a dedicated hardware solution is required to translate four-bit BCD codes into individual decimal selection signals without software overhead. It is suitable for designs requiring wide voltage tolerance and high noise immunity in noisy environments. Consider alternative packages if leaded termination or through-hole mounting is mandated by the board layout constraints.

Part Context

This device is part of the extensive 4000B series of CMOS logic ICs, which are industry-standard components known for broad compatibility and reliability. The MC14028 specifically fills the niche for BCD-to-decimal decoding, a fundamental function in legacy and modern digital interfaces alike. Its inclusion in the 4000B family ensures it shares common electrical characteristics with other gates and counters in the same series.

Replacement Considerations

The CD4028 is a primary functional equivalent within the same logic family. Verify pinout compatibility and electrical specifications against the original design requirements before substituting. Other generic BCD-to-decimal decoders may require significant circuit redesign due to differing input/output logic polarities or pin configurations.
