CD4028BEE4

Signal Switches, Multiplexers, Decoders Overview

The CD4028BEE4 is a BCD-to-Decimal decoder/driver manufactured by Texas Instruments. It operates within the CD4000B series of CMOS logic devices and is housed in a 16-lead plastic dual-in-line (PDIP) package. The component supports an operating supply voltage range from 3 V to 18 V and functions reliably across an extended temperature range of -55°C to +125°C. It provides true outputs for decoding binary-coded decimal inputs.

Signal Switches, Multiplexers, Decoders Feature Summary

• Performs conversion of four-bit binary-coded decimal inputs into one-of-ten active-high decoded outputs
• Features true output logic states corresponding directly to the input codes
• Designed with standard CMOS construction for compatibility with broad voltage ranges

Signal Switches, Multiplexers, Decoders Applications

• Decoding binary-coded decimal signals for display drivers
• Control logic circuits requiring decimal output selection
• Industrial control systems operating in extreme temperature environments

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the ordering suffix E4 confirms compliance with RoHS standards and indicates the use of matte tin (NIPDAU) lead finish. Confirm the package designation matches the required PDIP form factor for through-hole mounting. Ensure the part status is listed as Active Production before finalizing procurement plans.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single-channel BCD-to-decimal translation is required within a CMOS logic family. Consider the wide operating voltage window and high-temperature capability if the application environment exceeds standard commercial limits. Verify that the 16-pin DIP footprint aligns with the existing board layout constraints.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the CD4000B series, which encompasses various digital logic functions including decoders, counters, and gates. The CD4028B variant specifically addresses the need for direct decimal decoding without intermediate logic stages. The EE4 suffix denotes environmental compliance and specific material finishes compared to legacy versions.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The CD4028BE serves as a non-RoHS equivalent within the same product line. Other manufacturers offer cross-compatible parts such as the HEF4028B or MM54C42, though pinouts and electrical characteristics should be verified against official datasheets.
