U74AHC1G08G-AL5-R from UTC Unisonic Tech, in a SOT-353. 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 | A | input | Logic input A of the 2-input AND gate; input voltage must stay within 0 to 5.5 V (recommended operating range). |
| 2 | B | input | Logic input B of the 2-input AND gate; input voltage must stay within 0 to 5.5 V (recommended operating range). |
| 3 | GND | power_in | Ground reference for the device. |
| 4 | Y | output | AND gate output, high only when both A and B are high; output voltage is limited to 0 to VCC and output current is rated at ±25 mA absolute maximum. |
| 5 | VCC | power_in | Supply voltage, 2 V to 5.5 V recommended operating range (absolute maximum -0.5 to 7 V). |
