SN74LVC2G157DCU3 from Texas Instruments, in a VSSOP-8-0.5mm. 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 | Data input A; the datasheet gives the input voltage range as 0 V to 5.5 V. |
| 2 | B | input | Data input B; the datasheet gives the input voltage range as 0 V to 5.5 V. |
| 3 | Y | output | Inverted output (complement of Y, shown as Y-bar in the datasheet, which the text extraction drops); when the strobe G is high this output is high. Output voltage is limited to 0 V to VCC. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | Y | output | True data output; when the strobe G is high this output is low. Output voltage is limited to 0 V to VCC. |
| 6 | A/B | input | Selector input that chooses between data input A and data input B when the strobe G is low; input voltage range is 0 V to 5.5 V. |
| 7 | G | input | Common active-high strobe input; when high it forces Y low and the inverted output high, and when low the selected input is passed to the outputs. Input voltage range is 0 V to 5.5 V. |
| 8 | VCC | power_in | Positive supply; operating range is 1.65 V to 5.5 V. |
