MC74VHC1G135DBVT1G from onsemi, in a SC-74A-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 | B | input | Input B of the 2-input Schmitt-trigger NAND gate; input structures are protected for voltages up to 5.5 V regardless of the supply voltage. |
| 2 | A | input | Input A of the 2-input Schmitt-trigger NAND gate; input structures are protected for voltages up to 5.5 V regardless of the supply voltage. |
| 3 | GND | power_in | Ground reference pin for the device. |
| 4 | Y | output | Open-drain NAND output; the datasheet rates the output source/sink current at 8 mA at 3.0 V and 25 mA absolute maximum. |
| 5 | VCC | power_in | Positive supply pin, specified for 2.0 V to 5.5 V operation. |
