GT74LVC1G34S5

GTIC · Logic ICs · SOT-23-5

GT74LVC1G34S5 from GTIC, 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 NC unconnected No internal connection is made to this pin in the SOT23-5 package.
2 A input Buffer input, which accepts voltages up to 5.5 V and performs Y = A.
3 GND power_in Ground reference for the device.
4 Y output Buffer output with ±24-mA drive at 3.3 V, and the Ioff circuitry disables it to prevent backflow when the device is powered down.
5 VCC power_in Positive supply with an operating range of 1.65 V to 5.5 V.
