The Texas Instruments SN74LVC1G125YZAR is a single-gate non-inverting buffer with 3-state output from the 74LVC family. The scorch mark on a dead board might lead here, but the real question is whether you can get a replacement that brings the board back.
Supply range and drive — where it fits
Output drive is symmetric at 32mA for both high and low, which is enough to fan out to multiple CMOS loads or drive a small indicator LED through a series resistor. The single-bit, single-element configuration is meant for one signal path — think enable gating, clock buffering, or a reset line that needs a clean 3-state isolation.
The 5-DSBGA (1.4x0.9 mm) is a tiny wafer-level chip-scale package with no leads — just solder balls on the bottom. That saves board area but makes manual probing and hand-rework nearly impossible without hot-air and a microscope. If your assembly line isn't set up for DSBGA, or if you need to hand-troubleshoot prototypes, the same function in a SOT-23 or SC-70 package (like the SN74LVC1G125DBVR) will be easier to work with. The surface-mount mounting type is the only option here.
