Nexperia · Buffers, Drivers, Receivers, Transceivers · SOT-353

74AHC1G125GW from Nexperia, in a SOT-353. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OE input Active-LOW output enable input: the output Y is high-impedance (Z) when OE is HIGH, and the recommended input voltage range is 0 V to 5.5 V.
2 A input Data input of the buffer, with input voltage limited to 0 V to 5.5 V under recommended operating conditions (inputs are overvoltage tolerant to 5.5 V).
3 GND power_in Ground reference (0 V) for all voltages in the datasheet.
4 Y tri_state 3-state data output that follows A when OE is LOW and goes high-impedance when OE is HIGH; output current is limited to ±25 mA (absolute maximum).
5 VCC power_in Supply voltage, 2.0 V to 5.5 V for the 74AHC1G125 (absolute maximum -0.5 V to +7.0 V).
