74LVC1G126SE-7

Diodes Incorporated · Buffers, Drivers, Receivers, Transceivers · SOT-353

74LVC1G126SE-7 from Diodes Incorporated, 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 Output enable, active HIGH; when held LOW the Y output goes to high impedance (Z) per the function table.
2 A input Data input; inputs are tolerant up to 5.5 V, allowing mixed-voltage operation.
3 GND power_in Ground reference for the device.
4 Y tri_state Buffered data output with 3-state capability; high impedance when OE is LOW, and Y follows A when OE is HIGH.
5 VCC power_in Supply voltage, operating range 1.65 V to 5.5 V.
