MC14503BFELG

Overview

The MC14503BFELG is a hex non-inverting buffer with three-state outputs manufactured by onsemi. It operates within a supply voltage range of 3.0 Vdc to 18 Vdc and features high current source and sink capabilities. The device includes two disable controls: Disable A affects buffers 1 through 4, while Disable B controls buffers 5 and 6. It is housed in an SOEIAJ-16 package.

Feature Summary

• Hex non-inverting buffer architecture with three-state outputs
• High current source and sink capability for TTL loads
• Dual independent disable control inputs for versatile bus management

Applications

• Common bussing applications requiring tri-state isolation
• TTL compatible logic interfacing across full temperature ranges
• Pin-for-pin replacement for MM80C97 and 340097 devices

Procurement Notes

Verify the specific ordering suffix 'FEL' corresponds to the SOEIAJ-16 tape and reel packaging configuration. Confirm RoHS compliance status for the G suffix variant if lead-free materials are required. Ensure the component matches the exact pin assignment and electrical characteristics defined in the official datasheet before integration.

Selection Notes

Select this component when a hex non-inverting buffer with tri-state functionality is required. It supports dual disable inputs for flexible bus control. Verify that the operating voltage range of 3V to 18V aligns with system requirements. Consider the SOEIAJ-16 package dimensions for PCB layout compatibility.

Part Context

This part belongs to the MC14503B series of hex non-inverting buffers. It provides high drive strength suitable for driving multiple TTL loads. The device is designed for robust operation across industrial temperature ranges and offers versatility through its dual disable control scheme.

Replacement Considerations

The MC14503BFELG serves as a direct pin-for-pin replacement for the MM80C97 and 340097 components. Verify functional equivalence regarding electrical parameters and package dimensions before substitution.
