HEF4028BT,652

Overview

The HEF4028BT,652 is a CMOS logic integrated circuit manufactured by Nexperia, belonging to the HE4000B series. It functions as a Decade Decoder (1-of-10) with ten active-low outputs corresponding to binary-coded decimal inputs. The device is housed in a surface-mount SOIC-16 package. It operates on a single supply voltage ranging from 3 V to 15 V and supports an industrial temperature range of -40 °C to +85 °C.

Feature Summary

• Provides ten mutually exclusive active-low outputs for decoding four-bit binary inputs
• Designed for low power consumption typical of CMOS technology
• Compatible with standard 5 V logic systems while supporting wider voltage ranges

Applications

• Digital display drivers requiring BCD-to-decimal conversion
• Control logic circuits for sequential state indication
• Address decoding in memory or peripheral interfacing

Procurement Notes

Verify component authenticity through authorized Nexperia distributors. Confirm RoHS compliance status via official datasheets. Note that availability may be restricted; check current stock levels and lead times before finalizing procurement plans.

Selection Notes

Select this component when a 1-of-10 decoding function is required within a CMOS design. Ensure the operating voltage remains within the 3 V to 15 V range. Verify that the SOIC-16 package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the HE4000B family of high-speed CMOS logic devices. It serves as a digital decoder, converting binary inputs into one of ten distinct output lines. It is commonly used in conjunction with other logic gates for complex digital system control.

Replacement Considerations

Check for cross-reference parts such as CD4028 or MC14028 from other manufacturers. Ensure pin compatibility and electrical specifications match before substitution.
