MC74HC1G14DBVT1G from onsemi, in a SC-74A-5. 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. Leave floating or tie to a static level; do not use as a signal node. |
| 2 | A | input | Schmitt-trigger inverter input. Positive threshold VT+ ~3.15 V typ and negative threshold VT- ~2.3 V typ at VCC = 4.5 V, giving ~0.67 V hysteresis. Input leakage ±0.1 µA typ; input capacitance ~5 pF typ. |
| 3 | GND | power_in | Ground/0 V reference for the device. Absolute max DC supply current per ground pin ±25 mA. |
| 4 | Y | output | Inverted Schmitt-trigger output (Y = NOT A). Symmetrical CMOS push-pull drive with IOH = IOL = 2 mA; VOH ≥ 4.18 V at IOH = -2 mA / VCC = 4.5 V, VOL ≤ 0.26 V at IOL = 2 mA / VCC = 4.5 V. Absolute max output source/sink current ±12.5 mA. |
| 5 | VCC | power_in | Positive supply. Recommended operating range 2.0 V to 6.0 V; absolute max -0.5 to +6.5 V for SC-74A. Quiescent supply current ICC ≤ 1 µA at 25 °C. Decouple with a local 0.1 µF ceramic to GND. |
