Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type and suffix against official documentation, as ordering numbers may vary. Confirm RoHS compliance status through manufacturer datasheets or compliance statements. Check for obsolescence notices or lifecycle changes directly from onsemi or authorized distributors. Ensure the component matches the required operating temperature range and voltage specifications for the intended application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad buffer with 3-STATE outputs and high drive capability is required. Consider the ABT logic family for its speed and low power consumption characteristics. Verify that the SOP-14 package fits the PCB layout constraints. Ensure the application does not exceed the absolute maximum ratings for input voltage or current to prevent device damage.

Buffers, Drivers, Receivers, Transceivers Part Context

The 74ABT126 belongs to the ABT logic series, which combines the speed of Advanced Schottky TTL with CMOS low power consumption. Originally manufactured by Fairchild Semiconductor, the product line has been integrated into onsemi's portfolio. This specific part number represents the SOP-14 package variant, designed for surface mount applications requiring robust signal buffering and bus isolation capabilities.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-to-pin replacements within the same ABT series or compatible logic families. Verify that any substitute component meets the same voltage, current, and timing specifications. Consult manufacturer cross-reference guides for officially confirmed alternative part numbers.
