**lingxingic** · Inverters · SOT-23-5

SN74AHC1G04DB from lingxingic, 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 | n.c. | unconnected | Not connected (n.c.) according to the pin description table. |
| 2 | A | input | Data input of the inverter; recommended input voltage is 0 V to 5.5 V and the absolute maximum is -0.5 V to +7.0 V, with CMOS switching levels on the SN74AHC1G04 and TTL levels on the SN74AHCT1G04. |
| 3 | GND | power_in | Ground reference, 0 V. |
| 4 | Y | output | Data output of the inverter; output current is limited to ±25 mA and output clamp current to ±20 mA. |
| 5 | VCC | power_in | Supply voltage; recommended 2.0 V to 5.5 V for the SN74AHC1G04 and 4.5 V to 5.5 V for the SN74AHCT1G04, with an absolute maximum of +7.0 V. |
