# SN74AUC1G14MDBVREP

**Texas Instruments** · Inverters · SOT-23-5

SN74AUC1G14MDBVREP from Texas Instruments, 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. |
| 2 | A | input | Schmitt-trigger inverter input, 3.6-V tolerant (VI 0 to 3.6 V); unused inputs must be held at VCC or GND. |
| 3 | GND | power_in | Ground. |
| 4 | Y | output | Inverter output (Y = A inverted) with ±8-mA drive at 1.8 V; output voltage range 0 to VCC. |
| 5 | VCC | power_in | Supply voltage, operating range 0.8 V to 2.7 V (optimized for 1.65 V to 1.95 V). |
