Single buffer with 3-state output for mixed-voltage buses
It accepts a supply range from 1.65 V to 5.5 V, so it can bridge 1.8 V and 3.3 V logic domains without an external level shifter. The output can be placed in high-impedance mode via the output-enable pin, making it suitable for shared data buses or multiplexed signals.
Package and footprint — 6-SON (1x1 mm)
Housed in a 6-SON (1x1 mm) package (supplier device package 6-SON), this is a tiny, leadless package with a 0.5 mm pitch. The 6-XFDFN case requires careful soldering — no room for a probe point, so verify the layout before assembly. The small footprint saves board space on dense PCBs, but the lack of visible leads means visual inspection is impractical; X-ray or automated optical inspection is recommended for production.
The base product number is 74LVC1G126, and the series is 74LVC.
