The SN74LVC1G34DRYR: The 125°C ceiling is the junction limit — in a 105°C ambient with the 32 mA output driving a heavy load, the self-heating eats into that margin, so a thermal analysis at the board level is prudent if the output runs near the rated current continuously.
No, the SN74LVC1G125YZPR uses a 3-state output with an enable pin, while the SN74LVC1G34DRYR is a straight non-inverting buffer with push-pull output and no enable. The pinouts differ — the 1G125 has an OE pin that the 1G34 lacks — so a direct drop-in replacement requires a board spin or a bodge wire.
