MC74VHC1G05DTT1G from onsemi, in a TSOP-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 connect pin with no internal function stated in the datasheet pin assignment. |
| 2 | IN A | input | Inverter input that tolerates up to 7 V regardless of supply voltage, with recommended VIN of 0.0 to 5.5 V. |
| 3 | GND | power_in | Ground reference for the device. |
| 4 | OUT Y | passive | Open-drain inverter output (low or high-impedance Z) that needs an external pull-up resistor and can be pulled to between VCC and 7 V, with recommended VOUT of 0.0 to 7.0 V. |
| 5 | VCC | power_in | Positive supply pin with recommended operating range of 2.0 to 5.5 V and absolute maximum of -0.5 to +7.0 V. |
