The output can sink or source 8mA, which covers typical fan-out to one or two CMOS loads without needing a separate line driver. ## Supply voltage range — why 2V to 5.5V matters for BOM compatibility If your board already has a 3.3V rail for the MCU and a 5V rail for the sensor interface, this buffer can run off either without a level translator — just tie the supply pin to the rail that matches the signal swing you need. The 8mA output drive at both voltage extremes stays consistent, so fan-out doesn't collapse at the low end. ## Package and footprint — SC-70-5 on the board Housed in a 5-lead SC-70 (also known as SOT-353), the 74AHC1G125DCKTE4 takes up about 2mm x 2mm of board area. Keep the decoupling cap within 5mm of the supply pin — the 2V to 5.5V range doesn't impose special filtering, but a 0.1µF ceramic is the usual call.","metaTitle":"74AHC1G125DCKTE4 Buffer, Non-Inverting, 3-State, 2V-5.5V","metaDescription":"74AHC1G125DCKTE4 single buffer with 3-state output, 8mA drive, SC-70-5, -40°C to 125°C.
