It operates from 2V to 5.5V, making it suitable for mixed-voltage systems and battery-powered designs where the supply rail may vary. The output can be placed in a high-impedance state via the output-enable pin, allowing multiple buffers to share a bus without contention.
Supply voltage range and drive capability
At the lower end of the supply range, output drive drops, so verify the fan-out against the load's input current at 2V if you are running near the floor.
The 125°C upper limit is the junction temperature, so in a high-ambient enclosure you still have headroom before derating becomes necessary. No AEC-Q100 qualification is listed, so if you need automotive-grade traceability, check the AHC1G125 variant with that suffix.
Housed in a 5-pin SC-70-5 (also known as SOT-353), this is a tiny surface-mount package — about 2.0 mm × 1.25 mm. The pad pitch is 0.65 mm, so standard 0805 passives and a fine-tip iron are fine for rework, but a hot-air station is safer if the board is dense.
This is a straightforward BOM line to fill — no allocation risk, no end-of-life scramble.
