**TECH PUBLIC** · Buffers, Drivers, Receivers, Transceivers · SOT-553

TP74LVC1G07X5 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 internal connection. |
| 2 | A | input | Buffer input; VIH min 0.7×VCC at VCC 4.5-5.5V, absolute max input voltage -0.5 to +6.5V. |
| 3 | GND | power_in | Ground reference for the device. |
| 4 | Y | output | Open-drain output, high-impedance (Z) when A is high and low when A is low; can sink 24mA at 3.0V and 32mA at 4.5V. |
| 5 | VCC | power_in | Supply voltage, 1.65V to 5.5V operating range (absolute max 6.5V). |
