Diodes Incorporated · Buffers, Drivers, Receivers, Transceivers · SOT-25

74AHC1G125W5-7 from Diodes Incorporated, in a SOT-25. 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: Y follows A when OE is LOW and goes to high impedance (Z) when OE is HIGH, per the function table.
2 A input Data input with Schmitt-trigger action, tolerant of slow input rise and fall times; unused inputs should be held at VCC or GND.
3 GND power_in Ground reference pin.
4 Y tri_state 3-state data output with ±8 mA drive at 5.0 V; it enters a high-impedance state when OE is HIGH.
5 VCC power_in Supply voltage, operating range 2.0 V to 5.5 V (absolute maximum -0.5 V to 6.5 V).
