Procurement Notes

Verify that the component matches the specified Diodes Incorporated manufacturer part number 74AHC1G125SE-7. Confirm the package type is SOT353 as indicated by the 'SE' suffix. Ensure compliance with RoHS directives and lead-free finish requirements. Check datasheet DS35176 Rev. 1-2 for absolute maximum ratings and recommended operating conditions before integration.

Selection Notes

Select this component when a single-channel non-inverting buffer with 3-state control is required. It is suitable for applications needing CMOS low power consumption and high noise immunity due to Schmitt trigger inputs. Consider the 2.0V to 5.5V operating voltage range and ±8 mA output drive capability for load matching. Verify thermal resistance values if operating near temperature limits.

Part Context

FAQ

How is the 3-state output controlled?

The output enters a high-impedance state when a HIGH-level signal is applied to the Output Enable (OE) pin.

What is the input characteristic regarding signal transitions?

All inputs feature Schmitt trigger action, making the circuit tolerant for slower input rise and fall times.
