CD4028BMT

Signal Switches, Multiplexers, Decoders Overview

The CD4028BMT is a CMOS BCD-to-Decimal or Binary-to-Octal Decoder/Driver manufactured by Texas Instruments. It operates within a supply voltage range of 3V to 18V and supports a wide operating temperature range from -55°C to 125°C. The device features true outputs and is housed in a 16-SOIC surface-mount package with a width of 3.90mm. It provides high noise immunity and low power consumption typical of the 4000B series.

Signal Switches, Multiplexers, Decoders Feature Summary

• Performs conversion of Binary-Coded Decimal inputs to active-high decimal outputs
• Supports binary-to-octal decoding functionality
• Features true output logic for direct interface compatibility

Signal Switches, Multiplexers, Decoders Applications

• BCD to decimal decoding circuits
• Binary to octal decoding applications
• Digital display driver interfaces

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix (e.g., E4, G4) against the datasheet to confirm RoHS compliance status and manufacturing origin. Ensure the SOIC-16 package dimensions match the PCB footprint requirements. Confirm availability as some variants may be discontinued or subject to long lead times depending on the distributor.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single-channel decoder with ten active-high outputs is required for BCD or binary input signals. Consider the 3V to 18V supply range for flexibility in various logic families. Verify that the 16-pin SOIC package fits the assembly constraints and that the -55°C to 125°C temperature rating meets the environmental specifications.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the Texas Instruments 4000B series of CMOS logic devices. It is functionally equivalent to other manufacturers' CD4028 parts but may differ in electrical characteristics such as propagation delay and drive strength. The 'BM' designation typically indicates the military-grade or extended temperature variant in some contexts, though TI standardizes these under the 4000B family specifications.
