# SN74LV1T126DBVR-TP

**TECH PUBLIC** · Buffers, Drivers, Receivers, Transceivers · SOT-23-5

SN74LV1T126DBVR-TP from TECH PUBLIC, in a SOT-23-5. 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 | OE | input | Output enable input; a LOW level puts output Y in the high-impedance OFF-state, and floating this pin is not recommended. |
| 2 | A | input | Buffer data input with low-threshold levels (VIL max 0.8V at VCC 3V to 5.5V), tolerant up to 5.5V recommended. |
| 3 | GND | power_in | Ground. |
| 4 | Y | output | 3-state buffer output referenced to VCC, drives ±8mA at VCC=5.0V and is high-impedance when OE is low. |
| 5 | VCC | power_in | Supply voltage, 1.6V to 5.5V recommended operating (absolute maximum -0.5 to 7V). |
