# TP74LVC1G04X5

**TECH PUBLIC** · Inverters · SOT-553

TP74LVC1G04X5 from TECH PUBLIC, in a SOT-553. 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 connect pin; not internally connected per the SOT553 pin configuration. |
| 2 | A | input | Inverter input; accepts voltages up to 5.5 V (VIN max 5.5 V) allowing down translation to VCC. |
| 3 | GND | power_in | Ground pin, 0 V reference for the device. |
| 4 | Y | output | Inverter output Y = NOT A, with ±24 mA drive at VCC=3.3 V. |
| 5 | VCC | power_in | Supply voltage pin, 1.65 V to 5.5 V operating range. |
