Procurement Notes
Verify the specific suffix 'DT1G' against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the SC-70 package. Confirm RoHS compliance status through the latest datasheet revision. Check for any obsolescence notices or lifecycle changes directly from onsemi before finalizing procurement plans.
Selection Notes
Select this component when a single non-inverting buffer with three-state control is required in a compact surface-mount package. The VHC series offers speed and power characteristics suitable for general-purpose digital applications. Consider the 2 V to 5.5 V operating range for flexibility in system voltage design. Verify that the 8 mA drive current meets the load requirements of the connected circuitry.
Part Context
This part is part of the MC74VHC1G126 family of single non-inverting buffers with 3-state outputs. It is designed for use in portable and battery-operated applications due to its low power consumption. The device is automotive qualified according to AEC-Q100 standards, ensuring reliability in demanding environments. It serves as a key component in signal buffering and line driving tasks within digital logic systems.
Replacement Considerations
Check for direct substitutes such as MC74VHC1G126DFT1G or M74VHC1G126DFT2G, noting differences in packaging and reel specifications. Ensure functional equivalence regarding voltage ranges, output drive capabilities, and pinout compatibility before substitution.
