74LVC1G34QSE-7

Diodes Incorporated · Buffers / Drivers · SOT-353

74LVC1G34QSE-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 NC unconnected No connection.
2 A input Data input, tolerant to 5.5V regardless of VCC level; unused inputs should be held at VCC or ground.
3 GND power_in Ground.
4 Y output Data output (push-pull, Y = A) with ±24mA drive at 3.3V and IOFF protection that disables the output when powered down.
5 VCC power_in Supply voltage, operating range 1.65V to 5.5V (absolute maximum -0.5 to 6.5V).
