Product details

Single-gate buffer for ultra-low-voltage buses

The SN74AUP1G125YZPR: Its supply range from 0.8V to 3.6V makes it one of the few single-gate buffers that can operate directly from a 0.8V core rail or a 3.3V I/O bank without a level translator. The 4mA output drive is sized for light loads — think GPIO expansion, clock buffering, or enable gating on a low-power bus — not for driving a long trace or multiple fan-outs.

4 mA output — what it can and cannot drive

The 4mA source and sink capability is typical for the 74AUP family. It will cleanly drive a single CMOS input or a low-power LED indicator, but don't plan on switching a relay coil or a long ribbon cable. If your load budget exceeds 4mA per channel, you need a higher-drive family like 74LVC or 74AHCT.

Package reality: 5-DSBGA (1.4x0.9 mm)

Solder balls are the only connection. Plan for a pick-and-place machine and stencil.

Industrial temperature grade

It is not qualified to AEC-Q100, so it is not recommended for under-hood automotive or other high-reliability automotive applications without additional qualification.

Frequently asked questions

What is the output current rating of SN74AUP1G125YZPR?

The output can source or sink 4mA. This is a light-load buffer — suitable for driving a single CMOS gate input or a low-current LED, but not for high-fan-out buses or inductive loads.

Is SN74AUP1G125YZPR compatible with 1.8V logic?

Yes. The supply range of 0.8V to 3.6V covers 1.8V operation directly. The input thresholds scale with VCC, so at 1.8V supply the buffer accepts standard 1.8V CMOS levels without any external level shifting.
