SN74LVC1G126DC

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

SN74LVC1G126DC from lingxingic, 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 input; driving OE low places output Y in the high-impedance (Z) state per the function table.
2 A input Data input; the datasheet states the input is compatible with 3.3 V and 5 V logic levels, allowing mixed 3.3 V/5 V operation.
3 GND power_in Ground reference (0 V).
4 Y tri_state Three-state data output; rated for ±24 mA drive at VCC = 3.0 V and limited to VCC + 0.5 V in operating mode.
5 VCC power_in Supply voltage; recommended operating range is 1.65 V to 5.5 V.
