Product details

Single-gate buffer with 3-state output — SOT-23-5 footprint

The Texas Instruments SN74AHC1G125DBVR is a single-gate non-inverting buffer with a 3-state output, part of the 74AHC logic family. It operates across a wide supply range of 2V to 5.5V, making it suitable for mixed-voltage designs from 3.3V MCU I/O to 5V legacy logic. The output can be disabled (high-impedance) for bus sharing or line isolation. Packaged in a compact SOT-23-5, it saves board space on dense PCBs.

8mA output drive — fanout and load budget

With 8mA source and sink capability at both high and low output levels, this buffer can drive standard CMOS loads. The 3-state enable allows multiple buffers to share a data bus without contention.

No derating needed for most industrial applications; the 125°C ceiling covers under-hood and hot-enclosure scenarios.

RoHS3 compliant (lead-free, no exemptions).

Frequently asked questions

Does SN74AHC1G125DBVR support 5V operation?

Yes, the supply voltage range is 2V to 5.5V, so it works directly with 5V logic rails without level shifting.

Is SN74AHC1G125DBVR RoHS compliant?

Yes, it is ROHS3 compliant (lead-free).

What is the function of SN74AHC1G125DBVR?

It is a single non-inverting buffer with a 3-state output. When the output enable is active, the output follows the input; when disabled, the output goes high-impedance.
