MC14503BDR2G

Overview

The MC14503BDR2G is a non-inverting buffer manufactured by onsemi, belonging to the 4000B logic series. It features two independent elements, each configured as a hexagonal (6-bit) buffer with tri-state outputs. The device operates within a supply voltage range of 3V to 18V and supports surface-mount installation in a 16-SOIC package. It is designed for applications requiring high-noise immunity and low power consumption typical of CMOS technology.

Feature Summary

• Provides non-inverting buffering functionality with tri-state output control
• Integrates two independent buffer elements per package
• Supports wide operating voltage range suitable for various digital systems

Applications

• Digital signal buffering in microprocessor interfaces
• Address bus buffering for memory systems
• Data line isolation in communication circuits

Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the supplier provides valid traceability documents matching the manufacturer's part number format.

Selection Notes

Select this component when a non-inverting buffer with tri-state capability is required for 4000-series compatible designs. Consider the 16-SOIC package constraints and thermal dissipation characteristics relative to the application environment. Verify that the input voltage levels align with the driving source logic family.

Part Context

This part belongs to the MC14503B family of hex buffers with tri-state outputs. It is part of onsemi's broader portfolio of CMOS logic devices designed for general-purpose digital applications. The device complements other members of the 4000B series, offering standardized pinouts and electrical characteristics for system interoperability.

Replacement Considerations

Check for direct cross-reference part numbers from onsemi or other manufacturers that match the 16-SOIC package and tri-state hex buffer specification. Ensure functional equivalence regarding voltage ranges and output drive capabilities before substitution.
