SN74LV1T126DBVR from Texas Instruments, in a SOT-23-5. 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 | Active-high output enable. When OE is high, the output Y follows input A; when OE is low, Y is placed in the high-impedance (3-state) condition. Reduced-threshold CMOS input (VIH min ≈ 0.99V at 1.8V VCC / 2.0V at 5V VCC), 5V tolerant. |
| 2 | A | input | Data input A of the non-inverting buffer. Reduced input threshold enables translation from lower-voltage logic (e.g. 1.2V-3.3V) up to VCC-referenced CMOS levels. 5V tolerant regardless of VCC. |
| 3 | GND | power_in | Ground reference (0V) for the device. Connect to system ground with a low-impedance path; place VCC decoupling capacitor close to this pin. |
| 4 | Y | tri_state | Non-inverting 3-state output. Drives VCC-referenced CMOS logic levels (VOH ≥ 2.4V, VOL ≤ 0.4V) with 8mA drive at 5V, 7mA at 3.3V, and 3mA at 1.8V. High-impedance when OE is low. B-version output is compatible with AUP1G and LVC1G families. |
| 5 | VCC | power_in | Positive supply voltage input. Recommended operating range 1.6V-5.5V (absolute max 7.0V). Output logic levels are referenced to VCC. Decouple with a 0.1µF ceramic capacitor to GND close to the pin. |
