CD4028BF/3

Signal Switches, Multiplexers, Decoders Overview

The CD4028BF/3 is a CMOS Decimal Decoder/Driver belonging to the 4000/14000/40000 series, manufactured by Harris Corporation. It features true outputs and is housed in a ceramic DIP-16 package with glass-sealed construction. The device operates within a temperature range of -55 °C to 125 °C and supports a maximum load capacitance of 50 pF. It has a maximum output current (Iol) of 0.00036 A and contains one functional unit with 16 terminals. The component is not RoHS compliant and carries an EAR99 classification.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides decimal decoding and driving capabilities using standard input regulation.

Signal Switches, Multiplexers, Decoders Applications

• Digital logic systems requiring BCD-to-decimal conversion
• Binary-to-octal decoding applications
• Industrial control circuits operating at high temperatures

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify compliance requirements as the CD4028BF/3 is explicitly stated as non-RoHS compliant. Confirm that the ceramic DIP-16 package aligns with assembly specifications. Ensure the operating temperature range of -55 °C to 125 °C meets environmental demands. Check for availability from authorized distributors or surplus suppliers like Rochester Electronics, as original Harris production may be discontinued.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a robust, high-temperature capable decoder is required. The ceramic package offers superior durability compared to plastic variants. Verify that the single-function architecture fits the design constraints. Consider the 50 pF load capacitance limit for signal integrity. Ensure the true output polarity matches the downstream logic requirements.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the extensive 4000-series CMOS logic family produced by Harris Corporation. It serves as a fundamental building block for digital counting and display systems. The CD4028 variant specifically handles decimal decoding, distinguishing it from binary counters or other logic gates within the same series.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Cross-reference with Texas Instruments CD4028BMT or Harris CD4028BMTE4/G4 for alternative sourcing. Verify pin compatibility and electrical characteristics before substitution.
