74LVC1G240DBVRG4 from Texas Instruments, in a SOT-23-5. 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 | Output enable input: the output is disabled (high-impedance) when OE is high, and OE should be tied to VCC through a pullup resistor to keep the output high-impedance during power up or power down, with the minimum resistor value set by the driver's current-sinking capability. |
| 2 | A | input | Data input A of the inverting buffer, which accepts input voltages up to 5.5 V, with an absolute maximum input voltage rating of 6.5 V. |
| 3 | GND | power_in | Ground pin. |
| 4 | Y | tri_state | Inverting 3-state output Y, rated for ±24 mA output drive at 3.3 V and a continuous output current of ±50 mA absolute maximum. |
| 5 | VCC | power_in | Supply pin supporting 5 V VCC operation, with an absolute maximum supply voltage of 6.5 V. |
