Single buffer with 3-state output
The SN74LVC1G125DPWR is a single-channel non-inverting buffer from TI's 74LVC family, with a 3-state output that lets you disconnect the signal path by pulling the output enable pin high.
Housed in a 4-XFDFN exposed pad package (supplier device package 4-X2SON, 0.8x0.8 mm), this is a tiny footprint — about the size of a grain of pepper.
The base product number 74LVC1G125 is a standard TI catalog item; replacement availability is stable through authorized distribution. The DPWR suffix denotes the X2SON package on tape-and-reel; the same die in a different package (SN74LVC1G125YZPR) exists but shares the same electrical characteristics — the choice is purely board-space and assembly-process driven.
