**Texas Instruments** · Buffers, Drivers, Receivers, Transceivers · VSSOP-8

SN74AUP2G125DCUR from Texas Instruments, in a VSSOP-8. 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 | 1OE | input | Output enable for gate 1; when this input is high, output 1Y is disabled to the high-impedance state, and when low, 1Y follows 1A. |
| 2 | 1A | input | Data input for gate 1, which is 3.6-V I/O tolerant and has an input-disable feature that allows floating inputs. |
| 3 | 2Y | tri_state | 3-state output of gate 2, which is high-impedance whenever 2OE is high. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | 2A | input | Data input for gate 2, which is 3.6-V I/O tolerant and has an input-disable feature that allows floating inputs. |
| 6 | 1Y | tri_state | 3-state output of gate 1, which is high-impedance whenever 1OE is high. |
| 7 | 2OE | input | Output enable for gate 2; when this input is high, output 2Y is disabled to the high-impedance state, and when low, 2Y follows 2A. |
| 8 | VCC | power_in | Supply voltage, specified from 0.8 V to 3.6 V. |
