# SN74AHC1G04DCKR

**Texas Instruments** · Inverters · SOT-353

SN74AHC1G04DCKR from Texas Instruments, in a SOT-353. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection. Pin is not bonded to the die and may be left floating or tied to a static level. |
| 2 | A | input | Inverter logic input A. CMOS input with Schmitt-trigger action for tolerance of slow input rise/fall times. VIH = 3.85 V min at VCC = 5.5 V; VIL = 1.65 V max at VCC = 5.5 V. Input voltage range 0 to 5.5 V independent of VCC. |
| 3 | GND | power_in | Ground reference pin (0 V). All input and output voltages are referenced to this pin. |
| 4 | Y | output | Inverter logic output Y = /A. Push-pull CMOS output rated ±8 mA drive at VCC = 5 V (±4 mA at 3.3 V, ±50 uA at 2 V). VOH ≥ 3.8 V at 8 mA / VCC = 4.5 V; VOL ≤ 0.44 V at 8 mA. |
| 5 | VCC | power_in | Positive supply voltage input. Recommended operating range 2 V to 5.5 V; absolute maximum 7 V. Quiescent ICC max 10 uA at 5.5 V. Bypass with a local 0.1 uF ceramic capacitor to GND. |
