SN74LV1T126DCKR from Texas Instruments, in a SC-70-5. 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 | OE | input | Output enable, active high; when LOW, output Y is in high-impedance state |
| 2 | A | input | Input A; accepts input voltage from 0V to 5.5V with supply-dependent threshold levels |
| 3 | GND | power_in | Ground reference voltage |
| 4 | Y | tri_state | 3-state output referenced to VCC; drives HIGH when OE=H and A=H, drives LOW when OE=H and A=L, high-impedance when OE=L |
| 5 | VCC | power_in | Positive supply voltage; operating range 1.6V to 5.5V per recommended operating conditions |
