MC14028BCPG

Overview

The MC14028BCPG is a CMOS BCD-to-decimal decoder manufactured by onsemi in a 16-pin PDIP package. It converts 8421 BCD inputs into one-of-ten decoded outputs and supports 3-bit binary inputs for octal decoding with output D forced low. The device operates within a supply voltage range of 3.0 Vdc to 18 Vdc and withstands ambient temperatures from -55 °C to +125 °C. It features diode protection on all inputs, positive logic design, and low outputs on illegal input combinations.

Feature Summary

• Converts 8421 BCD codes to decimal outputs or 3-bit binary codes to octal outputs
• Includes diode protection on all inputs for static voltage safeguarding
• Ensures low outputs on all illegal input combinations
• Capable of driving two low-power TTL loads or one low-power Schottky TTL load

Applications

• Code conversion circuits
• Address decoding systems
• Memory selection control
• Demultiplexing applications
• Decimal digit display readouts

Procurement Notes

Verify the specific ordering suffix 'G' confirms the lead-free package status as documented in the manufacturer's ordering information table. Confirm that the PDIP-16 package type matches the required mechanical footprint for the target PCB layout. Ensure compatibility with the specified operating temperature range and supply voltage requirements before finalizing procurement.

Selection Notes

Select this component when a single-chip solution is required to decode BCD signals into ten distinct active-high lines. It is suitable for designs needing expanded decoding capabilities through cascading multiple units. Consider its ability to interface directly with low-power TTL loads if mixed-logic family integration is necessary within the system architecture.

Part Context

This part belongs to the MC14028B series of standard CMOS logic devices. It serves as a direct functional equivalent to the CD4028B decoder. The series provides reliable code conversion and decoding functions within the broader family of onsemi standard logic integrated circuits designed for general-purpose digital applications.

Replacement Considerations

The datasheet explicitly states the device is similar to the CD4028B. Verify pinout and electrical characteristics compatibility before substituting.
